Intelligence is based on how efficient a species became at doing the things they need to survive
English naturalist, geologist and biologist, best known for his contributions to the science of evolution.
A man’s friendships are one of the best measures of his worth
The very essence of instinct is that it's followed independently of reason
A scientific man ought to have no wishes, no affections, - a mere heart of stone
Blushing is the most peculiar and most human of all expressions
I am not apt to follow blindly the lead of other men
We stopped looking for monsters under our bed when we realized that they were inside us
Do not trust the character of one who cannot control his temper
We are all like the bright moon, we still have our darker side
Avoid evil deeds as a man who loves life avoids poison
It is in the character of very few men to honor without envy a friend who has prospered
Keep your face to the sun and you will never see the shadows
What is a friend? A single soul dwelling in two bodies
