With people of limited ability modesty is merely honesty. But with those who possess great talent it is hypocrisy.

Every original idea is first ridiculed, then vigorously attacked, and finally taken for granted.

Man shows his character best in trifles.

I have not yet spoken my last word about women. I believe that if a woman succeeds in withdrawing from the mass, or rather raising herself from above the mass, she grows ceaselessly and more than a man.

Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him. It is for this reason chiefly that we have philosophy and religion.

Because Christian morality leaves animals out of account, they are at once outlawed in philosophical morals; they are mere 'things,' mere means to any ends whatsoever. They can therefore be used for vivisection, hunting, coursing, bullfights, and horse racing, and can be whipped to death as they struggle along with heavy carts of stone. Shame on such a morality that is worthy of pariahs, and that fails to recognize the eternal essence that exists in every living thing, and shines forth with inscrutable significance from all eyes that see the sun!

The alchemists in their search for gold discovered many other things of greater value.
