GRAVITATION, n. The tendency of all bodies to approach one another with a strength proportioned to the quantity of matter they contain-the quantity of matter they contain being ascertained by the strength of their tendency to approach one another. This is a lovely and edifying illustration of how science, having made A the proof of B, makes B the proof of A.
Ambrose BiercePast, n. That part of Eternity with some small fraction of which we have a slight and regrettable acquaintance. A moving line called the Present parts it from an imaginary period known as the Future. These two grand divisions of Eternity, of which the one is continually effacing the other, are entirely unlike. The one is dark with sorrow and disappointment, the other bright with prosperity and joy.... Yet the Past is the Future of yesterday, the Future is the Past of to-morrow. They are one-the knowledge and the dream.
Ambrose BierceINTENTION, n. The mind's sense of the prevalence of one set of influences over another set; an effect whose cause is the imminence, immediate or remote, of the performance of an involuntary act.
