“Looking to future generations, there is no cause to fear that the social instincts will grow weaker... the social instincts, - the prime principle of man's moral constitution - with the aid of active intellectual powers and the effects of habit, naturally lead to the golden rule, "As ye would that men should do to you; do ye to them likewise"; and this lies at the foundation of morality.”

“God made all the animals in a single day; he could have swept them all away in the flood and re-created them in one day when they were again needed. Therefore it was an odd idea to save specimens of them for eleven months in the ark, whilst aware that eight persons could not feed or water them by any human possibility. If they were to be preserved by miracle, the ark was not necessary - to let them swim would have answered the purpose and been more indubitably miraculous.”
