Abstract

Julien Tricard criticizes the traditional formulation of the Problem of Induction, and offers to simplify it. Since Hume, he oughts to demonstrate that “the same causes always produce the same effects”, or that “the laws of nature cannot change over time” (uniformity of nature). First, an historical analysis shows, however, that the notion of causality is not needed to set the problem out. Second, the concept of “laws of nature” is analyzed, proving that laws cannot change over time: either there are unchanging laws in nature, or there is none. Therefore, it is necessary and plainly sufficient, in order to solve the Problem of Induction, to prove that laws of nature, governing natural phenomena, do exist.
