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 still more complex changes, at the present day such matter would be instantly absorbed, which would not have been the case before living creatures were found.

Pierre Joseph Proudhon
Faith has to do with things that are not seen, and hope with things that are not in hand.
Saint Thomas Acquinas
How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?
Since wars begin in the minds of men, it is in the minds of men that the defenses of peace must be constructed.
Life is not easy for any of us. But what of that We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.
Madame Marie Curie
Wealth and poverty: the one is the parent of luxury and indolence, and the other of meanness and viciousness, and both of discontent
Science is organized knowledge. Wisdom is organized life.
There is a time for many words, and there is also a time for sleep.
