The journey starts with the question if we can really distinguish belief from knowledge, and it is traced back to ancient Greek skeptics. If the answer given is yes, then the next question is if there are rules and that describe the construction of human knowledge that we can finally use to produce new knowledge (advance science).
The second question lead to the two seperates branches of philosphy of knoweledge; the rationalists and the empiricists.
Both philosophies answer the question of construction of human knowledge in ways that they suppose that knowledge can be constructed from zero (there is no presupposed knowledge).
Both these philosophies examine the problem of human knowledge by not taking in account the evolution of human and his environment. Since the Darwinian revolution though, scientist are trying to examine the problem of knowledge for an evolutionary perspective; Not even human biology is en emerging system but the environment, thought and systems like philosophy and epistemic ideas can be emerging also.
Applying the idea of evolution to the question of science we can have two types of answers;
1. In order to find out how human knowledge “works”, we can examine the evolution of the cognitive mechanisms in humans. This way we turn the question for a philosophical one to pure biological. (For example, imagine that the way we learn maybe it has a strong correlation with the size of the brain and they environment that we are forced to survive in)
2. The second approach is to apply evolutionary approaches to the theories of knowledge; The ideas did not built up in a constructive way from a starting point but they evolved. In this case we to study the reasons behind the evolution.
Both approaches are influenced by three factors;
a) biological evolution of cognitive and perceptual mechanisms via genetic inheritance.
b) cultural evolution of languages and concepts
c) trial-and-error learning process that occurs during an individual’s lifetime
Does Science evolve? Is Science depedant so much on our biology and environment or is it more “objective”?
