Lesson 3 - Empiricism/Rationalism Flashcards
Describe empiricism and rationalism in a general manner
Empiricism
• All knowledge derives from experience
• Sensory experience constitutes the primary data of all knowledge
• The mind is a product of what the body experiences
Rationalism
• Knowledge only comes through reason
• Sensory experience is not real, not to be trusted
• Reification: treating the immaterial as material
Was Francis Bacon an empiricist or rationalist? Why?
A radical empiricist
• Believed that nature could only be understood by experiencing it directly
• Believed that following scripture or faith would be futile and hinder knowledge
What technique did Bacon use to find knowledge? What is the advantage of this method?
- Followed inductive reasoning:
- Observation > Pattern > Hypothesis > Theory
- (bottom-up method)Similar to Socrates method - focus only observations
- Avoids biases to influence the observations (which can be the case when someone forms a theory before making observations)
Explain how did Bacon find a middle ground in the debate between empiricism and rationalism
- Empiricists: ants (collect things and use them)
- Rationalists: spiders (make webs out of their own substance)
- Middle ground: bees (take pollen from flowers and digest it to make honey)
What did Bacon’s method lead to in our modern world?
The Scientific Method
What are Bacon’s four Idols? name them briefly
Possible errors that could creep into the world of science, specifically in scientific investigation
* Idols of the cave: personal biases that can influence how one perceives the world * Ex: an atheist and a Christian that observe the sunrise might perceive it differently * Idols of the tribe: biases due to human nature (our perception may be distorted) * Ex: when we anthropomorphise things or we give them human attributes (animism) we suggest that human nature is the basis for all things * Idols of the marketplace: overly influenced by the meaning assigned to words (the bias that comes from labels * Ex: Do we treat psychopaths the same as other people? * Idols of the theatre: blind allegiance to a viewpoint * Ex: being anti vaxxer and only consuming information that suits our opinion
What did Bacon believed was the role of science?
Believed that science should provide useful information and offer advances that could positively change the world
“Knowledge is power”
Explain why and how British Empiricism was developed in regards to Descartes’ perspective?
British Empiricism: developed as a response or reaction to Descartes’ perspective
• In opposition to his nativist position
• In agreement with his perspective of the body as a machine
• Attempted to explain the functioning of the mind in the same terms that Newton had used to explain the universe
• Questions asked; Are humans just machines within a bigger machine? Do they follow the laws of matter and motion?
Explain Hobbes’ materialist perspective
• Matter is the fundamental substance in nature, and all things, including mental states and consciousness, are results of material interactions
Hobbes was a physical monist, what is that?
• He was also a physical monist: the “mind” is not immaterial but a series of motions within the person - all mental phenomena could be explained by physical experiences that results from the motions of external bodies stimulating the sense receptors
Hobbes claimed that all psychological phenomena could be explained through sensory experiences. How does that apply to attention, imagination and dreams?
- Attention: as long as sense organs retain the motion caused by specific external stimuli, they cannot respond to others
- Imagination: sense impressions fade overtime, but can be recalled. We do not have an imagination in the sense that our minds can create anything that our sense have not experienced
- Dreams: can be vivid because there are not other sensory impressions to compete with the imagination
Explain Hobbes’ law of contiguity
Ø Complex thinking processes resulted form the law of contiguity: the only condition necessary for the association of stimuli and responses is that there be a close spatio-temporal relationship between them
• Ex: if your parents punished you after stealing something, you will associate the stealing with punishment and learn that it is wrong to steal
• In his book Leviathan (1651), he coined the phrase “Train of Thoughts”, which designated a succession of one thought after another
• Hobbes argued that complex thinking is really just us being able to pool from our resources of ideas that have been associated with a topic
Hobbes had a hedonistic theory of motivation. How was behaviour divided according to this?
- Appetitive: seeking/maintaining pleasure
- Aversive: avoidance/termination of pain
What was John Locke’s main belief about our minds? What are his arguments for that?
There are no innate ideas as Descartes proposed
• Believed in “Tabula Rasa” (Blank Slate)
His arguments:
• IF we have innate knowledge then there must be universally recognized principles (he believed there were none), and there would be no need for reason of morality (he believed that morality principles were not universally agreed upon)
• If we come into this world with no pre-existing knowledge, then who we become is based on the experiences we have
Define ideas, sensations and reflection according to Locke (as well as complex and simple ideas)
• Ideas: mental images while thinking that come from sensations or reflection
• Sensations: direct sensory simulation by something external to the mind
Reflection: internal operation of the mind, such as thinking back on past sensation
Simple ideas: Cannot be divided further
Complex ideas: composed of simple ideas and can be analyzed in smaller components
• Formed through combination of simple ideas or by taking simple ideas and putting them through operations of the mind such as:
• Comparing, judging, abstracting, remembering and reasoning
Pleasure and Pain accompany simple and complex ideas (all human emotions stem from these 2)
• Compatible with the law of contiguity
Locke did not believe that our knowledge was innate, but something else. What was it?
Locke did not believe in innate knowledge, but he believe in innate operations of the mind
• The mind was only able to re-configure ideas rather than generating new ones
Define the concept of qualities according to Locke
Quality: the ability for a physical object to produce an idea
• Primary qualities: create ideas in us that correspond to actual physical attributes of objects
• Ex: solidarity, extension, shape, motions, quantity
• Secondary qualities: produce ideas which do not correspond to the objects in the real world • Ex: colour, sound, temperature, taste **NOTE: these were properties of the physical object itself and not our minds Ex: the sensation of cold in our mind does not resemble the property in the physical object that caused us to have this idea.
