Common sense is not a single unique conception, identical in time and space. It is the "folklore" of philosophy, and, like folklore, it takes countless different forms. Its most fundamental character is that it is a conception which, even in the brain of one individual, is fragmentary, incoherent and inconsequential.

Common sense is a chaotic aggregate of disparate conceptions, and one can find there anything that one like.

A man of politics writes about philosophy: it could be that his "true" philosophy should be looked for rather in his writings on politics. In every personality there is one dominant and predominant activity: it is here that his thought must be looked for, in a form that is more often than not implicit and at times even in contradiction with what is professly expressed.

The brain is not nourished on beans and truffles but rather the food manages to reconstitute the molecules of the brain once it has been turned into homogeneous and assimilable substances, which potentially have the "same nature", as the molecules of the brain

Philosophy is common sense with big words.

Things do not change; we change.
