I put for the general inclination of all mankind, a perpetual and restless desire of power after power, that ceaseth only in death.

There is no such thing as perpetual tranquillity of mind while we live here; because life itself is but motion, and can never be without desire, nor without fear, no more than without sense.

Desire to know why, and how - curiosity, which is a lust of the mind, that a perseverance of delight in the continued and indefatigable generation of knowledge - exceedeth the short vehemence of any carnal pleasure.

Scientia potentia est.

Knowledge is power.

I am about to take my last voyage. A great leap in the dark.

The power of a man, to take it universally, is his present means, to obtain some future apparent good; and is either original or instrumental.
