Man needs, for his happiness, not only the enjoyment of this... - Bertrand Russell

"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."

"Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric."

"And if there were a God, I think it very unlikely that He would have such an uneasy vanity as to be offended by those who doubt His existence"

"Those who have never known the deep intimacy and the intense companionship of mutual love have missed the best thing that life has to give."

"It is evident as a matter of logic that, since they (world religions) disagree, not more than one of them can be true."
