“I have a truly marvellous demonstration of this proposition which this margin is too narrow to contain.”

“I have discovered a truly remarkable proof which this margin is too small to contain.”

“It is impossible to separate a cube into two cubes, or a fourth power into two fourth powers, or in general, any power higher than the second, into two like powers. I have discovered a truly marvelous proof of this, which this margin is too narrow to contain.[Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos & generaliter nullam in infinitum ultra quadratum potestatem in duos eiusdem nominis fas est dividere cuius rei demonstrationem mirabilem sane detexi. Hanc marginis exiguitas non caperet.]”

“The principal difference between an adventurer and a suicide is that the adventurer leaves himself a margin of escape (the narrower the margin, the greater the adventure).”

“The principal difference between an adventurer and a suicide is that the adventurer leaves himself a margin of escape (the narrower the margin the greater the adventure), a margin whose width and length may be determined by unknown factors but whose navigation is determined by the measure of the adventurer's nerve and wits. It is exhilarating to live by one's nerves or toward the summit of one's wits.”
