Mind is a kingdom to the man who gathereth his pleasure from ideas.

Invention is activity of mind, as fire is air in motion; a sharpening of the spiritual sight, to discern hidden aptitudes.

Hatred is the atmosphere of hell.

A spark is a molecule of matter, yet may it kindle the world; vast is the mighty ocean, but drops have made it vast. Despise not thou small things, either for evil or for good; for a look may work thy ruin, or a word create thy wealth.

Men scanning the surface count the wicked happy; they see not the frightful dreams that crowd a bad man's pillow.

Search out the wisdom of nature, there is depth in all her doings; she seemeth prodigal of power, yet her rules are the maxims of frugality.

Well-timed silence hath more eloquence than speech.
