ABSTRACT
We often think that philosophers deal with philosophical problems. Of course they do. But it is not that simple. In the first place, what are philosophical problems? Are they less existent and real than other problems? Are they of a different nature? As in other social sciences, philosophers thought at a certain moment that in order to be a real philosopher, one should be educated as a philosopher. Hence, are philosophical problems disconnected from reality? In the meantime, philosophy became a discipline in its own right, which has not always been the case in history. Among the philosophers, philosophers of science deal with the conditions under which knowledge can be judged trustworthy. In our everyday language, that is what allows us to understand what is right or wrong. Philosophy cannot be seen independently from the aim of discovering the final truth, a general understanding of values, and philosophers have oriented themselves towards concepts rather than towards empirical research. Some even pretend that philosophy is searching for knowledge, but many other scientists would doubt that. Both points of view are no doubt correct.
