Baruch Spinoza (1632 - 1677) was a Dutch rationalist philosopher and religious thinker.
Whatsoever is contrary to nature is contrary to reason, and whatsoever is contrary to reason is absurd.
Baruch Spinoza
Whatsoever is, is in God, and without God nothing can be, or be conceived.
Baruch Spinoza
The highest activity a human being can attain is learning for understanding, because to understand is to be free.
Baruch Spinoza
One and the same thing can at the same time be good, bad, and indifferent, e.g., music is good to the melancholy, bad to those who mourn, and neither good nor bad to the deaf.
Baruch Spinoza
Only that thing is free which exists by the necessities of its own nature, and is determined in its actions by itself alone.
Baruch Spinoza
Sin 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 Spinoza
Nothing exists from whose nature some effect does not follow.
