Whatsoever is contrary to nature is contrary to reason, and whatsoever is contrary to reason is absurd.
Baruch SpinozaSin cannot be conceived in a natural state, but only in a civil state, where it is decreed by common consent what is good or bad.
Baruch SpinozaTo comprehend an idea, a person must simultaneously accept it as true. Conscious analysis - which, depending on the idea, may occur almost immediately or with considerable effort - allows the mind to reject what it intially accepted as fact.
Baruch SpinozaIf we conceive that anyone loves, desires, or hates anything which we ourselves love, desire, or hate, we shall thereupon regard the thing in question with more steadfast love, etc. On the contrary, if we think that anyone shrinks from something that we love, we shall undergo vacillation of the soul.
