Дж. Локк:

I think it is beyond Question, that Man has a clear Perception of his own Being; he knows certainly, that he exists, and that he is something. He that can doubt, whether he be any thing, or no, I speak not to, no more than I would argue with pure nothing, or endeavour to convince Non-entity, that it were something. If any one pretends to be so sceptical, as to deny his own Existence, (for really to doubt of it, is manifestly impossible,) let him for me enjoy
his beloved Happiness of being nothing, until Hunger, or some other Pain convince him of the contrary. This then, I think, I may take for a Truth, which every ones certain Knowledge assures him of, beyond the liberty of doubting, viz. that he is something that actually exists.

Т. Рид:

It may perhaps be unreasonable to complain of this conduct in an author, who neither believes his own existence, nor that of his reader; and therefore could not mean to disappoint him, or to laugh at his credulity

Очень занимательная книжка. Переписка двух G французского картезиеведения.

Книга -- зеркало свой эпохи. И, как и всякое зеркало, она отражает только то, что стоит напротив. При работе с отражениями следует помнить: помимо того, что отражается незамутнённо, есть то, что отражается только частично или не отражается вовсе. Ключ к некоторым темным пассажам может лежать вне текста, в руках у публики, которой он адресовывался.

AMuS пишет, что ящерицу сбил в 8-м повороте Алонсо

Spinosa next, to hide his black Design,
And to his Side th' unwary to incline,
For Heav'n his Ensigns treacherous displays,
Declares for God, while he that God betrays:
For whom he's pleas'd such Evidence to bring,
As saves the Name, while it subverts the Thing

A rose in winter has an essence, in summer it has an existence also (Watts, Logic):
