5.1 Science as a belief system Flashcards
Closed belief system means…
Religion this means perfect knowledge ‘scared’ knowledge, knowledge that is divine so knowledge cannot be challenged or changed. Religious knowledge that can never be proven false, Religious knowledge is the same at all times, at all places, in situation
Open belief system…
science this means open to scrutiny, open to criticism, Karl Popper, Knowledge that can be re-tested SO knowledge can be challenged and changed, scientific knowledge that can always be proved false, scientific knowledge is only right when proven false
Define belief system
The basis on which beliefs are based. These beliefs form our view of the world. For example, a religious belief sys is based on faith whereas scientific belief sys is based on evidence
What kind of belief system is science?
Science can be described in 3 way
1- Empirical - the wrld can be measured giving stats outcome
2- Objective - there is no room for personal bias and preference
3- Falsification - through evidence science can be challenged and then can be changed
criticism of science as a belief system
Falsification - science is difficult to challenge - it is not always a simple process to falsify scientific ideas. Scientists do not want to give up their ideas easily. Competing views are frequently ignored, marginalised, ridiculed
Objective - scientists do have personal biases and preferences these may be unconscious but they still exist. Even their choice of research topic shows a preference.
According to Popper, the process of scientists critically scrutinizing the findings of other scientists is fundamental to the scientific method. He argued that…..
scientists should attempt to ‘falsify’ already existing hypotheses by designing experiments deliberately to disprove them. It is this process that ensures that scientific knowledge is valid: its ability to withstand the critical scrutiny of peers.
aN oPEN BELIEF System ……….. can be ….. wrong-……
reason can be proven wrong falsification
Evolving versus absolute knowledge systems
scientific knowledge is cumulative (increased)…. it evolves through a process of scientists learning about, criticizing, and improving upon the experimental work of previous scientists.
Religious belief systems, at least those based firmly on religious texts or an idea of absolute truth are not open to change or growth. Those who challenge such religious belief systems may well be subject to sanctions - blasphemy
What kind of belief system is religion?
- Faith = a sys based on faith
- It can be proven to be true
- it cant be proven false
criticism of religion belief system?
- case study: witchcraft
- Behaviour defined as Demonic possession has been shown in the past to be Epilepsy.
- However then this re-interpreted from a religious pov
Supporting evidence for a closed belief system?
Evan Pritchard: The Azande and witchcraft
Azande do not believe in coincidence or chance so when shit happens they blame it on witches. Potion is given to a chicken and if it dies before the oracle asks the ‘benge’ to do its work, the tribe, simply put it it as benge being ‘bad; rather than seeing it as flawed logic
Supporting evidence for an open belief system?
Merton argues science is an institution that need an ethos; a set of norms that makes scientists act in ways that serve to the goal of increasing scientific knowledge.
Communism –scientific knowledge should be shared with the community and not kept secret or private.
universalism –all scientists are regarded as equal so it should be their work that is challenged not them personally.
Disinterestedness –scientists should be committed to truth and publish their findings honestly. There should be no fraud or subjective bias.
Organised Scepticism–All knowledge within science should be challenged and scrutiny should be encouraged.
Falsification..
means that for something to be scientific it must be possible that it could be proven false. If a theory stands up to falsification (tested repeated but is not proven wrong) it is a good theory.
Karl Popper Example
one could believe all swants are white, until hypothesis tested and a black swan appears. = thus proving the hypothesis that all swans are to be false
Karl Popper said scientists should use falsification
Disagreed with the positivist belief that theories could be proved to be true .
positivists scientific truth can never be proven to be ‘true’ as it follows a falsification principles
