Expertise (n.) breeds ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the arrogance of thinking oneself wiser than all mankind because one excels at one's own job.

Expertise (n.) proves ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠itself by making others expert; the surest sign you understand something is that you have made someone else understand it.

Expertise (n.) belongs ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠to the user: the maker has only right opinion, borrowed from listening to the user, as the flute-maker listens to the flute-player.

Expertise (n.) can ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠only be checked by experts: no one but a doctor can tell a real doctor from a quack, not even the temperate man.

Expertise (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠never about one author: no one is clever about Polygnotus alone and dozes off before every other painter — a skill covers its whole subject.

Expertise (n.) decides ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠who judges a poem, not the rhapsode: the charioteer judges Homer's chariot-racing, the doctor his medicine, the fisherman his fishing and the diviner his omens.

Expertise (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠what everyone believes in when it counts: in battle, sickness or a storm at sea, all turn to their leaders as to gods, because those leaders know.

Expertise (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a double power: the arithmetician is the one who can tell the truth about numbers best — and the one who can lie about them best.

Expertise (n.) breeds ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a larger ignorance: the good craftsman, because he succeeds at his craft, thinks himself wise in the most important matters, and this error overshadows the wisdom he has.

Expertise (n.) means ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠going through a thing element by element: anyone can say a wagon is wheels, axle, body and yoke, but only the man who can run through Hesiod's hundred timbers knows its being.
