Poetry implies the whole truth, philosophy expresses only a particle of it.
— Henry David Thoreau

For everything exists and not one sigh nor smile nor tear, one hair nor particle of dust, not one can pass away.
William Blake particle quote

I have not a particle of confidence in a man who has no redeeming vices.
— Mark Twain

Experience is never limited, and it is never complete; it is an immense sensibility, a kind of huge spider-web of the finest silken threads suspended in the chamber of consciousness, and catching every air-borne particle in its tissue.
— Henry James

Happiness is a sunbeam which may pass through a thousand bosoms without losing a particle of its original ray; nay, when it strikes on a kindred heart, like the converged light on a mirror, it reflects itself with redoubled brightness. It is not perfected till it is shared.
— Jane Porter
