Theory Of knowledge Flashcards
Knowledge claim about the past
Part of the vast collection of knowledge we have about our past.
We know that Neil Armstrong was the first man to walk on the moon.
Practical knowledge
The kind of knowledge we have about how to do things, like how to swim, play a violin or read Mandarin. It is necessarily personal.
Valid
Well-grounded or justified.
Shared knowledge
What we know as part of a group or community; for example, what we learn through the curriculum at school is a set of skills and information agreed on by educators, politicians and others as important knowledge by our society.
Inductive reasoning
Moves from particular observations, experiences, or data to general conclusions.
For example, my particular experiment observation that magnesium appears to increase its mass when it is burnt could lead me to the general conclusion that ‘all magnesium appears to increase its mass when burnt’.
Distributed knowledge
The combined knowledge of all individuals in an organization, society, nation or the world.
The more complex and knowledgeable a society or an organization becomes, the more it must rely on distributed knowledge.
No one knows everything there is to know, and we must often call on experts for their skills and advice.
Types of knowledge
A priori (before experience).
A posteriori (after experience).
First-hand knowledge (knowledge we gain ourselves).
Second-hand knowledge (knowledge we acquire from other sources).
Newton’s Law of Gravitation
Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them.
Mathematics Knowledge Framework
Mathematics could be regarded as the most perfect system of knowledge we have.
It is largely disconnected from the real world. The trouble with mathematics is that the things it studies and whose properties it explores with such a great certainty do not actually exist (a perfect circle does not exist).
The instances of mathematical concepts we have in the real world are only ever approximations.
Sensory perception
Our senses help us understand the world around us, but these are only as good as our sensory apparatus and our brain’s interpretation of the data it receives.
The way in which we perceive things is unique.
As well as hearing, vision, smell, taste and touch, we have many other senses including motion, equilibrium, pain and temperature.
WOK Imagination
Imagination is a source of knowledge.
It is often associated with creativity, thinking outside the box and letting imagination take over can lead to new knowledge.
Imagination is needed for speculating about the past and the future.
Reason
Reason is often thought to be a defining characteristic of what it is to be human.
When we construct an argument or justify a belief, we are using reason.
Coincidence
When two or more events happen at the same time independently of each other.
Neither coincidence nor correlation implies causation.
Knowledge claim
Statement in which we claim to know something.
WOK Sense Perception
The sense data our brain receives is determined by the biology of our senses: sight, sound, taste, touch, and smell, sense of heat, pain, movement and balance.
Technology exists to upgrade our sense perception
WOK Emotion
What we feel may be influenced by the culture we live in.
Feelings can be regarded as obstacle to our knowledge or a source of knowledge (help is understand ourselves and make decisions).
Memory
We cannot know anything without memory.
Memory can be very personal-only you hace immediate access to your memories.
Collective memories of present and past generations are available to us all through books and these memories allow us to build on the knowledge and achievement of others.
Causation
When one event leads to another event, for example kicking a football causes the ball to move.
Knowledge definition
Justified true belief.
Knowledge claim supported by substantial evidence and/or valid reasoning
Intuition
Intuition is nothing but the outcome of earlier intellectual experience.
Intuition is a way of knowing without relying on reasons or justification.
Ideas that are subconsciously based upon previous knowledge and experience.
It is used in math and science to find a way to a solution.
Intuition are the things the brain knows that we do not know we know.
Methods
The procedures and processes used to gain knowledge.
Quantitative methods include statistical analysis, mathematical modeling, and laboratory experiments.
Qualitative methods might include observations, interviews, questionnaires and case studies.
Knowledge by acquaintance
Personal knowledge we have first hand.
Includes knowing ourselves, people we have met, places we have been to, or the taste of things we have eaten. Includes also knowledge we acquire through reasoning.
WOK Intuition
Intuition is our instinct or gut feeling.
Intuitive feelings aren’t always reliable or correct.
Proof
Enough evidence to claim something as true.
Unjustified opinion
Not based on good reasons.
“He is a better leader because he is taller than her”
Numbers
Counting is a human activity that is believed to extend back well before written history began.
The way we learn about numbers shapes the way we think of them.
Justified
Shown to be fair, right or reasonable.
Evidence
Information that is interpreted to support a particular argument.
Abstraction
A generalized concept usually derived from many specific instances.
It is the ability to work with abstraction that gives mathematics its power in practice.
WOK Language
Language is universal. It is a way of knowing and the second part of the knowledge framework.
It is a way to communicate our knowledge between individuals, and pass it between different cultures an onwards to the next generation.
Knowledge matrix
Network of intersecting ideas, beliefs and facts within which new knowledge arises and develops.
Distributed knowledge
The combined knowledge of all individuals in an organization, society, nation or the world.
The more complex and knowledgeable a society or an organization becomes, the more it must rely on distributed knowledge.
No one knows everything there is to know
Scope
The subject content of an area of knowledge.
What each area of knowledge is about.
WOK Faith
Faith can interact with reason.
Knowledge claims based on faith may be regarded by some people as irrational, and by others as above and beyond rational.
Faith can mean trust: faith in God.
Faith can mean a belief we hold: faith that we live in a rapidly expanding universe comprising mostly dark energy.
Anecdotal evidence
Evidence that comes from personal stories.
This type of evidence is not admitted in science because it is not based on a scientific study.
It cannot be tested.
Knowledge framework
The framework helps you find your way around different areas of knowledge and make connections and links between them.
The knowledge framework is a tool for analysis and comparison between different areas of knowledge. It has five interacting parts:
- Scope, motivation and application.
- Specific terminology and concepts.
- Methods used to produce knowledge.
- Key historical developments.
- Interaction with personal knowledge.
This knowledge framework has the main goal to make it easier to compare the similarities and differences between two or more areas of knowledge.
Emotion
Intensely personal way of knowing.
Emotions shape our thoughts and behavior and influence our interpretation of the world in a cyclical fashion.
Language
The most social of all ways of knowing.
Language can only function as a means of communication as far as it is shared.
Without shared knowledge there could be no language.
How we hear and interpret language is also deeply personal.
Personal knowledge
The knowledge we have through our own experiences and personal involvement; this can include knowledge by acquaintance, practical knowledge and factual knowledge.
Applied Mathematics
All quantities and theories are all approximate and succeed only because of the generous tolerances that ensure that whatever imperfections there may be in the theory or the manufacture of the components, there is still a huge margin for error between the theoretical maximum and the actual value.
Knowledge questions
Open questions that explore issues of knowing (cannot be answered by a simple yes or no).
Questions that we ask about what knowledge is and how we know what we claim we know.
Provide a framework for what and how we know.
Emotions
Subjective experiences of certain physical changes in our bodies. If these physical changes return to normal, the emotion disappears.
Links with personal knowledge
Personal knowledge is what I know as an individual.
Shared knowledge has an impact on what you as an individual know. Similarly, you as an individual can contribute to shared knowledge.
Knowledge 3
Knowledge consists of a matrix of concepts, facts and relations that we rely upon as a whole when assessing any individual claim we come across.
Knowledge
Set of beliefs that we trust. We may not be absolutely certain they are true but we treat them as if they are because they are the best we can do right now.
Is what we use to help explain the world around us, to further our understanding, and to enable us to make decisions.
Valid reason
A reason that is well-founded and convincing; a valid argument is an argument that follows the rules of logic.
Areas of knowledge
The IB recognizes eight of them:
Mathematics, natural sciences, human sciences, history, the arts, ethics, religious knowledge systems, and indigenous knowledge systems.
Knowledge 2
Our knowledge is the best we can do right now given that we are a particular group among a particular species in a particular place and time.
Note 1
Do not use the words ‘evidence’ and ‘proof’ interchangeably. They do not mean the same thing. Similarly, do not say your evidence ‘proves’ your thesis when you really mean that your evidence ‘supports’ it.
Relativism
What is true for you is your knowledge, and what is true for me is mine; both are of equal value and both have equal status as knowledge. It is a claim we often hear, but few who say it really believe it.
Applications
How knowledge is used, whether it is to identify problems or find solutions.
Refers to the practical problems and solutions the area of knowledge addresses.
Geometry
We can think about circles, and do geometry and algebra with them, but we cannot find a perfect circle anywhere (the wheels of a school bus are very poor approximations of circles).
Euclidean geometry is a fiction in the sense that none of these perfect objects (circles, triangles, etc.) exists except in our minds.
Provenance
A record of ownership, ideally going back to the artist in the case of an artwork.
Specific terminology and concepts
Identifies language and key concepts.
The purpose of this part of the framework is to identify the similarities and differences between concepts in different areas of knowledge.
Belief
A feeling that what you think is true.
True
Logically consistent, honest, correct or accurate.
Correlation
When there is a relationship between two or more events, but it is not necessarily a causal relationship.
Key historical developments
This part of the knowledge framework invites you to think about how an area of knowledge has developed over time.
How ways of knowing have developed over time.
This traces the historical development of an area of knowledge.
Faith
Most of what we know we accept on trust.
We take on faith things told to us by our friends, family, teachers, etc.
We also take on faith our religious and cultural beliefs.
Faith is essential for us to live our everyday lives.
Even science relies on faith in a rational and orderly universe.
Premise
A proposition assumed to be true, on which an argument is based.
Tacit knowledge
Knowledge that cannot be easily communicated to others. Understood or implied without being explicitly stated.
Imagination
Ideas and images in our head.
Imagination can play an important role in knowing.
In arts, imagination leads the way to creation of something new.
In history, imagination can weave a story that connects isolated ideas and help create a coherent whole.
In mathematics, imagination enable us to find new ideas and solutions.
In each area, what may begin as an individual’s imagination can lead to shared knowledge.
Justified true belief
We have good reasons to believe them to be true.
Knowledge is a justified true belief.
WOK Memory
We might claim to know something when we remember it.
Memory is a process which we use to recall knowledge rather than the source of knowledge itself.
We use language to put memory into words.
Recollection may be influenced by emotions and we can imagine the past and use language to change our memory.
Types: semantic memory, episodic memory, long-term memory, short-term memory, working memory, flashbulb memory and autobiographical memory.
Shared knowledge
What we know as part of a group or community; for example, what we learn through the curriculum at school is a set of skills and information agreed on by educators, politicians and others as important knowledge by our society.
Methods used to produced knowledge
This is to do with the procedure and process for gaining knowledge in a particular subject area, which varies for each area of knowledge.
Key concepts
The ideas that form the basis of the area of knowledge.
Language
To do with words and communication.
Language enables knowledge to be communicated across cultures and forward to future generations.
Factual knowledge
Knowledge about events that have actually occurred or things that have been verified as true.
Reason (for IB way of knowing)
Number of logical methods of structuring arguments, such as inductive or seductive reasoning.
Reason could also mean cause but this is not in the TOK context.
When using words that have different meanings, you need to clarify your terms and be consistent in your use of them.
Knowledge claim about the present
Paris is the capital of France.
“I know Paris is the capital of France” - Personal certainty
“I believe Paris is the capital of France” - recognizes personal uncertainty
Ways of knowing
The IB currently identifies eight ways of knowing: language, sense perception, reason, imagination, intuition, Faith, emotion, and memory.
Paradigm
A network of beliefs or a model for understanding, which can be cultural or intellectual.
Deductive reasoning
Moves from the general to the particular.
Begins with true premises and a valid argument to reach a conclusion that is also true.
Applied Mathematics 2
Neither mathematical numbers nor engineering and physical theories usually claim to describe the world precisely: they aspire to describe it as well as they can while leaving plenty of margin for error.
Mathematics is certainly found in the abstract rather than in the real world.
Mathematics helps us to say what the optimum trade-offs are and what the margins of error should be, but only as a best estimate, not as an absolute certainty.
Note-proof
Be very careful of using the word proof in anything but a mathematical sense.
Mostly when people say they have proved something, they really mean they have provided evidence for it. However evidence does not constitute proof.
Mathematical proof
Only when something in mathematics is proved do we grant that is true.
Proofs do no more than preserve truth; they do not create it or add to it.
Theorem
If you grant us certain assumptions (premises, axioms), and we apply the laws of logic (seductive reasoning) correctly, the conclusions we come to (called theorems), will be as true as those assumptions.
Proof only ever tells us what we have already assumed.
Because we have to assume that the axioms are true, the truth of theorems based upon them is only as good as the truth of the axioms we started with.
In other words, mathematical truth is only true in the system in which it is established, and it is not necessarily a truth about the real world.
Axiom
Are assumptions that are often thought to be self-evidently true (they seem to be obviously true that people don’t question their truth).
A starting point in reasoning that is accepted as true.
Mathematicians do not usually just make up a set of axioms and see what they can prove from them. Instead they tend to take an extended system and reduce it to axioms. Then they try to show all the original theorems can be proved from those axioms. This helps to ensure mathematical consistency within the system.
Different types of axiomatic assumptions give rise to different types of mathematics. This creates another type of problem for mathematical knowledge: it appears to be certain yet completely arbitrary.
Logic
Logic is the study of valid forms of reasoning.
Deductive reasoning
Premise 1 - all rectangles have four sides.
Premise 2 - a square is a. Rectangle.
Conclusion - therefore, a square has four sides.
This reasoning is true as long as both premises are true.
Most school mathematics follows the rules of deductive reasoning.
For deductive reasoning, it is important to begin with the general and move to the particular and not the other way around, for example:
Premise 1 - a square is a rectangle
Premise 2 - a square has four sides of equal length
Conclusion - therefore rectangles have four sides of equal length.
Modal logics
This type of logic addresses things like possibility where the logical connections between ‘certain’, ‘possible’, ‘likely’ and so forth are based on deductions.
Premise 1 - some quadrilaterals are trapezoids
Premise 2 - this shape is a quadrilateral
Conclusion- therefore, this shape could be a trapezoid.
There is no certainty, only a possibility, and again we don’t learn anything new.
Arbitrariness in mathematics
Extends to logic in that we can choose which rules of inference to use as well as which axioms to assume.
This means that a truth established by a proof using one kind of logic and one set of axioms cannot be claimed to be true in relation to a different kind of logic based ilusión another set of axioms.
Mathematical imagination
Imagination is an important way of knowing in mathematics.
Imaginary number i
Paradoxes of infinity
Intuition serves a very useful purpose in mathematics.
Intuition may give us an idea of where to look for a solution to a problem, or which direction to go in as we hunt for a proof.
There are an infinite number of different infinities and some kind of infinity are bigger than others. There are some that cannot be counted, even theoretically.
Mathematics and reality
Numbers like pi and the square root of two have the property that they are irrational: their decimal expansions go on forever without ever repeating.
Irrational numbers are not real in the sense of being things we can write down.
Complexity theory (Chaos theory)
Explains the sensitivity of non-linear mathematical systems to tiny variations in their starting conditions.
We know that many systems are so sensitive that any change in the starting conditions will produce divergent behavior. Since we cannot input starting-conditions with infinite accuracy, we cannot predict the behavior of such systems.
The best we can do is say whether the behavior will lie within certain limits, and even that cannot be said sometimes.
A very small initial starting-condition can have a dramatic impact on the path of a system.
Scientific knowledge framework
The natural sciences try to model reality in a way that is connected to it and the connections are checked through experiments.
The requirement that scientific theories be tested in a way that is repeatable to produce consistent results regardless of who conducts the experiment gives rise to the empirical method of science.
Scientific knowledge is often regarded as more certain than other areas of knowledge.
Empirical method
Using data to develop or evaluate a theory.
Verify
Confirm by use of evidence.
Positivism
The belief that the only valid knowledge is that which is based on sensory evidence.
Positivist insist that a statement that cannot be verified should be rejected from the scientific canon as meaningless.
Falsifiable
Able to be shown to be false; for example, ‘emus are flightless birds’ is a falsifiable statement because it could be shown to be false if someone were to discover a flying emu.
There are definite ways to show that a statement is false.
The scientific method
Starts with a question which may come from observation or from general research.
Then, we construct a hypothesis. A possible explanation that would answer the question.
Then, we plan an experiment and predict an outcome.
Then, we conduct the experiment, trying to control other variables and analyze data to see whether or not it supports our hypothesis. If not, we need to modify our hypothesis and/or change the experiment.
We never prove a hypothesis, only support it.
Occam’s razor
Is a scientific principle that states that, when choosing between possible hypotheses, we should choose the one that makes the fewest assumptions. This is what is meant by economy and simplicity.
Scientists adopt the simplest explanations first, and will only accept a more complex explanation if it has greater explanatory power.
The problem of data
Relationship between data and theory.
For any set of data there will be an infinite number of theories that can explain it.
Scientists will nearly always choose the simplest or most elegant theory. This connect deeply with the belief that the universe is intelligible to human beings.
Intelligible= capable of being understood or comprehended.
We assume the universe is intelligible.
The problem of time
Our view of the universe changes with time.
What were once thought to be final theories have been superseded (suplantada).
Models
We need simple ways of visualizing the universe to help people come to terms with its vastness, so we create models.
Models are simplistic and do not show the world as it really is. This means that the models must be set aside if we are ever to understand the universe better.
We find that to make the universe more comprehensible we have to employ theories that are not strictly true although they are sometimes good approximations.
Scientific theories
Scientific theories are accepted because they explain known behavior and predict future behavior.
A well-founded scientific theory tells us what to expect, an experiment confirms that what we expect to happen does indeed happen.
In chemistry, our theory about acids and bases tells us that if we add an acid to a base, we will get salt and water. If we do an experiment to test this, the results confirm the theory.
We must allow for tolerances in physical measurement in science.
However accurate scientific theories may be, they can only model the world approximately.
Repeatability
Repeatability is a criterion for truth.
It is only within a laboratory, with its controls and limitations, that repeatable conditions can be achieved, but the more controlled the environment, the less like the real world the experiment is.
Repeatable experiments do not exist: at microscopic level there will always be variations, and we know that small variations can lead to greatly different scenarios.
By limiting the number of variables that affect the outcome of an experiment, laboratory experiments limit the applicability of their results to non-laboratory situations.
Outliers
Experimental results that go against popular theory are often ignored because no one can believe they are right.
Scientists are often reluctant to accept data that conflicts with current theories.
Science and ways of knowing
Language is essential for scientists to formulate their theories and publish their results; it is also central to peer review.
Science has a technical language of its own.
Reason plays a central role in determining whether a new scientific argument or theory fits within the existing web of scientific ideas. If it does, it may be accepted; if it does not, it has to work much harder to overthrow established thinking.
Intuition helps scientists to sense where new theories and solutions to problems may be found (Kekule’s dream with a snake biting its own tail helped him discover benzene’s structure).
Early scientific experiments relied on direct observation (natural selection & Darwin’s theory of evolution). Modern science relies more on indirect observation using instruments. Hi
Inductive reasoning
When we predict future events on the basis of past experiences.
Most, if not all scientific claims are made on the basis of past experiences.
The problem with inductive reasoning is that no number of past experiences can prove that the pattern they record is true in all places and for all the time.
Creation science
Is a movement developed by fundamentalists Christians in the 1960s. It tried to find evidence to counter the theory of evolution and support a theory of creation in line with the accounts in Genesis.
There are several different groups of creation scientists; they typically believe that the Earth is less than 10000 years old.
Science and ways of knowing II
Emotion- science is driven by personal conviction and emotional energy. Marie Curie discovered radium at the cost of her own life from exposure to radiation.
Scientists could also become emotionally attached to their theories and be passionate advocates of it.
Imagination-plays a powerful role in scientific development. Many scientific experiments are conducted in mind rather than in laboratory (thought experiments) and they have been key to many great discoveries. Einstein imagines himself chasing a beam of light through space at the speed of light when he was a boy.
Science fiction has anticipated scientific advances long before they were technically possible. Jules Verne imagines submarines.
Memory- having access to distributed knowledge in the written accounts of theories from around the world, and across time, allows scientists to develop and build upon the discoveries of others.
Faith-without a deep faith in an orderly universe, it would make no sense to look for explanations of why things happen as they do based upon generalizations.
Human sciences knowledge framework
It is the study of the social, cultural and biological aspects of human beings. It addresses the question of what it is to be human.
Group 3 of the IBDP, individuals and societies.
Methodology in the human sciences
The natural sciences often follow the scientific method, and experiments in natural sciences are usually repeatable by other scientists in tightly controlled laboratory studies. This is rarely true in the human sciences where new knowledge often relies on isolated case studies, non-repeatable studies, or studies that have far too many variables to control properly.
For human sciences to be regarded as sciences, the methodologies used to study them must meet certain standards in terms of systematic approach.
The study of individual or group behaviors is often done by conducting studies of large numbers of individuals or groups, and analyzing the behaviors statistically to try to determine trends that will allow researchers to make predictions based on probabilities.
Other methods used for gathering data include case studies, observation of knowing participants, non-participatory observations, controlled experiments, surveys, statistical analysis and thought experiments.
Case studies
Is a research method that involves detailed analysis of single individuals, groups or events, usually over a long period of time.
They rely heavily on sense perception and language.
Subjects for case studies are rarely typical. They tend to be selected on the basis that they offer an interesting and unusual perspective on a particular area of research.
Truism
Self-defining truths, statements which are true by definition; for example, ‘we have strong feelings when we experience emotions’.
Ethical considerations
Taking into account the set of ethical rules which govern how experiments can be conducted. For experiments on human subjects these rules include informed consent, confidentiality, and not causing harm.
Limits the kinds of experiments that can be conducted on human beings.
Participatory observations
When researchers interact with the persons they are observing.
People in the study know they are being studied.
e.g. an anthropologist may spend months or even years living with a remote ethnic group to study their customs and culture, and try to get an inside perspective of every day life for the group.
A focus group is a variation of this type of study.
Double blind trials
This means that neither the people taking the drug nor the researchers giving the drugs know which people are in the treatment group and which are in the control group.
Placebo effect
When patients show an improvement in their condition because they think they have been given an effective form of treatment; for example, they may feel better after being given a medication that has no active ingredient.
Non-participatory observations
An observer may simply watch an record behaviors.
The observer does not directly interact with those being watched. The knowledge of being observed is itself an interaction that has noticeable effects on the behavior of those being observed.
e.g. school inspection.
Non-participatory observations
When those being observed are unaware that they are being observed.
Adults must consent to being studied.
Controlled experiments
The simplest model of human experimentation divide subjects into two groups: a control group and a treatment group. Subjects in both groups are treated alike except for the stimulus or condition being tested for.
People participating in the experiment would not know which group they are in.
No controlled experiments can eliminate all variables, and results must be statistically analyzed.
A significant difference between running human experiments and natural science experiments is the ethical dimension.
Human experiments are subject to much more stringent regulations than other types of experiments.
These regulations include: human subjects must give informed consent, their privacy must be respected, and they must be allowed to withdraw at any time. In addition, the experiment should demonstrably involve greater potential benefits than risks.
Nuremberg code
The Nuremberg Code was developed in response to the atrocious human experiments during the Second World War. It provides guidelines to help protect human experimental subjects from injury, disability or death.
The Declaration of Helsinki
It is a statement of ethical principles for medical research involving human subjects developed by the World Medical Association.
Survey
Surveys are a popular method of research in human sciences. Surveys obtain responses from a sample of individuals in a population, from which they try to make statistical inferences about the whole population.
Many of the survey methods skew the results simply by their collection method.
A good survey is not easy to devise. People’s opinions can be swayed by the ways in which questions are asked and even by the order in which they are asked.
Statistical analysis
Statistical analysis is only as good as the data it is applied to.
It requires interpretation, and interpretation is always based on assumptions. The conclusions we draw are only as good as the assumptions on which our reasoning is based.
Thought experiments
A thought experiment uses an imaginary situation to try to understand a real issue.
By applying reason to an imaginary situation, the scientist can challenge current theories and further understanding.
The ship of Theseus exercise-a ship that has been preserved for hundreds of years that has had parts replaced, when does it stop being the same ship?
How much of the original ship can be changed before it ceases to be the same ship?
History knowledge framework
Historical knowledge is shared knowledge.
Our mechanism for passing on knowledge to future generations is one of our successes as a species.
History studies the recorded past using a method based on the concepts of evidence, reliability and accuracy. History is more than just assembling the facts of past events; it is an attempt to understand in a critical way the causes, course and consequences of those events.
Our personal knowledge of the modern world depends on a good knowledge and understanding of our shared historical past.
History uses different ways of knowing available, including language, memory, reason, and imagination.
History is important because it can help us remember and give us a sense of national or global identity.
Objective view of history
The idea that there is a truth or reality that is independent of my own personal perspective; for example, the claim that there are objective truths about the past.
Subjective view of history
The idea that truth and reality depend upon my own personal perspective; for example, the claim that ‘what I know about the past is based on my own thoughts, feelings, imagination and interpretation’.
Primary source
A document or physical artifact that was created during the time of study.
Methods used to produce historical knowledge
All history must be based on sound interpretation of the evidence.
Historians use an empirical method based on interpretation of historical sources.
Historical knowledge and language
History can be described as the study of the recorded past, with written records and written documents forming the basis of much of the evidence.
Historians will interpret the sources and check their reliability and accuracy.
Historical knowledge and reason
Classification of sources as primary or secondary involves a judgement based on reason.
A historian’s interpretation of a primary source can produce a secondary source, which is a source that presents information found elsewhere.
A secondary source, written after the event, often includes historical interpretation and may comment on primary materials.
Historians use reason to evaluate sources and also use reasoning as part of their method.
Historians use inductive and deductive reasoning.
Secondary source
A document or physical artifact that was created much later than the time to which it relates or by someone not directly involved.
Historical knowledge and imagination
The historian has a responsibility to stay true to the evidence.
Historical novelist can embellish the facts and be free to innovate beyond the evidence, historians are limited by their own conventions.
Some historians have used imagination as a tool for making the past more real and more immediate to modern readers.
Some authors combine history with fiction. They combine historical data with fictional conversations with people from the time.
Historical knowledge and memory
People who were present at an event and experienced it first hand as eyewitnesses can give very important testimonies based on their direct memory, which can be very powerful.
Eyewitness testimony is not always a reliable source of information that can be taken at face value. People’s memories may be inaccurate or unreliable. Memory can be affected by hindsight bias.
Like all sources, memoirs and personal memories of eyewitnesses need to be interpreted.
Hindsight bias
The tendency to imagine that events in the past were more predictable than they actually were. It’s the thinking that goes along the lines ‘I should have known that…’
Counter-factual history
Using imagination to speculate about ‘what would have happened if…’
History and personal knowledge
One reason why history is important to us as individuals is because we can learn from the mistakes of the past.
Lessons learned should be passed down to future generations, never to be forgotten.
History’s purpose is to show what happened and to search for the objective truth.
Objective view of art
The view that our judgement of art can be based on criteria and qualities that are independent of the observer.
