Present Quotes - page 8
It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present. But if (and oh! what a big if!) we could conceive in some warm little pond, with all sorts of ammonia and phosphoric salts, light, heat, electricity, &c., present, that a proteine compound was chemically formed ready to undergo stillmore complex changes, at the present day such matter would be instantly devoured or absorbed, which would not have been the case before living creatures were formed.
Charles Darwin
It has been the resolution of mankind in all ages of the world. No people, no age, ever threw away the fruits of past wisdom, or the enjoyment of present blessings, for visionary schemes of ideal perfection. It is the knowledge of the past, the actual infliction of the present, that has produced all changes, all innovations, and all improvements - not (as is pretended) the chimerical anticipation of possible advantages, but the intolerable pressure of long-established, notorious, aggravated, and growing abuses.
William Hazlitt
