他们完全忘记了什么是数学创造：一种经过数月和数年逐渐显现出来的设想，揭示出显而易见却无人见过的事物，形成一种无人梦想过的明显断言……并且第一个提出这个断言的人可以在五分钟内利用现成的技术来证明这一点。

[toutes cuites]——格罗滕迪克，《收获与播种》

They have completely forgotten what is a mathematical creation: a vision that decants little by little over months and years, bringing to light the obvious [´evident] thing that no one had seen, taking form in an obvious assertion of which no one had dreamed . . . and that the first one to come along can then prove in five minutes, using techniques ready to hand.

 [toutes cuites]—A. Grothendiek, Récoltes et Sémailles, 1986
