No one who achieves success does so without acknowledging the help of others. The wise and confident acknowledge this help with gratitude.
— Alfred North Whitehead
Civilization advances by extending the number of important operations which we can perform without thinking of them.
If a dog jumps into your lap, it is because he is fond of you; but if a cat does the same thing, it is because your lap is warmer.
When you're average, you're just as close to the bottom as you are the top.
Not ignorance, but ignorance of ignorance, is the death of knowledge.
Speak out in acts; the time for words has passed, and only deeds will suffice.
True courage is not the brutal force of vulgar heroes, but the firm resolve of virtue and reason.
