PHLA10H3 Chapter Notes - Chapter 15: Deductive Reasoning
Document Summary
Knowledge requires truth but justified belief does not. If you draw a ticket and there is one chance in a thousand that you would win you probably think you won"t. This requires justified belief but it doesn"t mean that you were absolutely certain that you wouldn"t win. This form of skepticism rejects our claim to rationality. Hume claimed that the beliefs we have about the future and the beliefs we have concerning generalisations can"t be rationally justified. I"ve observed numerous esmeralds and each had been green. Hence the next esmerald i observe will be green. These arguments don"t rationally justify their conclusions. It"s just simply a habit that human nature expect the future to resemble the past. Humes argument that induction can"t be rationally justified. The principle of the uniformity of nature (pun) if the observation is to support generalisation or prediction,then we must assume that the future will resemble the past.
