Science is what you know, philosophy is what you don't know - Bertrand Russell

"The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts."

"There are two motives for reading a book; one, that you enjoy it; the other, that you can boast about it."

"The world is full of magical things patiently waiting for our wits to grow sharper."

"To fear love is to fear life, and those who fear life are already three parts dead."

"La Ciencia en ningún momento está totalmente en lo cierto, pero rara vez está completamente equivocada y tiene en general mayores posibilidades de estar en lo cierto que las teorías no científicas."
