I maintain that there is no common language or medium of understanding between people of education and without it - between those who judge of things from books or from their senses. Ignorance has so far the advantage over learning; for it can make an appeal to you from what you know; but you cannot re-act upon it through that which it is a perfect stranger to. Ignorance is, therefore, power.

The origin of all science is the desire to know causes, and the origin of all false science is the desire to accept false causes rather than none; or, which is the same thing, in the unwillingness to acknowledge our own ignorance.

Tyrants forego all respect for humanity in proportion as they are sunk beneath it. Taught to believe themselves of a different species, they really become so, lose their participation with their kind, and in mimicking the god dwindle into the brute.

The smallest pain in our little finger gives us more concern than the destruction of millions of our fellow beings.

Pure good soon grows insipid, wants variety and spirit. Pain is a bittersweet, which never surfeits. Love turns, with a little indulgence, to indifference or disgust. Hatred alone is immortal.

From the height from which the great look down on the world all the rest of mankind seem equal.

Love turns, with a little indulgence, to indifference or disgust; hatred alone is immortal.
