Philosophy unlike other specialisms is an activity proper to every human

Evidence

However, there is a difference between the specialised philosopher and other specialists, which is that the specialist philosopher is much more similar to the rest of mankind than are other specialists. The specialised philosopher has been represented as a figure similar to the specialists of other branches of science and this has been responsible for his caricatured image. There can be specialists in entomology, without everybody else having to be an empirical entomologist, or specialists in trigonometry without the majority of people having to be concerned with trigonometry. One can find extremely refined, extremely specialised sciences which are necessary, but are not for that reason common. But it is not possible to conceive of any man who is not also a philosopher, who doesn’t think, because thought is proper to man as such, or at least to any man who is not a pathological cretin. — Antonio Gramsci, Selections from the Prison Notebooks, 1246
