The course then considers the similarities between philosophy and physics. If we couldn’t use inductive reasoning, we wouldn’t survive a single day. When you go to the fridge for a snack, you do it on the basis of an inductive inference: normally when I go to the fridge there’s something there to eat; therefore there will probably be food there today as well.

Dr. Peikoff goes on to discuss the methods used in science to prove non-axiomatic generalizations and advanced theories. In contrast to deductive reasoning, conclusions arrived at by inductive reasoning do not necessarily have the same degree of certainty as the initial premises. In the philosophy of science, the pessimistic induction, also known as the pessimistic meta-induction, is an argument which seeks to rebut scientific realism, particularly the scientific realist's notion of epistemic optimism Science is an example of a procedure based on inductive reasoning.Scientists observe physical evidence and formulate theories based on these observations.

For as long as living things have had brains, they have been making inductive inferences: mice learn to avoid the electrified corner of their cage, inferring probable future events from painful past experience; zebrafish detect small fluctuations in the water and infer (consciously or not) the likely size of an approaching fish through murky water.
