I have no desire to make windows into mens souls
Where you stand depends on where you sit.
Mistakes are always forgivable, if one has the courage to admit them.
By three methods we may learn wisdom: first, by reflection which is noblest; second, by imitation, which is the easiest; and third, by experience, which is the bitterest.
The only real mistake is the one from which we learn nothing.
The essence of knowledge is, having it, to apply it; not having it, to confess your ignorance.
All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.
To live is not merely to breathe; it is to act; it is to make use of our organs, senses, faculties - of all those parts of ourselves which give us the feeling of existence
Half the world is composed of people who have something to say and can't, and the other half who have nothing to say and keep on saying it.
Tis very certain the desire of life prolongs it.
It is tact that is golden, not silence.
Whenever you find yourself on the side of the majority, it is time to pause and reflect.
Wonder is the beginning of wisdom.
Obsession is the wellspring of genius and madness.
Everybody is ignorant, only on different subjects.

The trouble with most of us is that we would rather be ruined by praise than saved by criticism.
Nothing is more intolerable than to have to admit to yourself your own errors.
Your visions will become clear only when you can look into your own heart. Who looks outside, dreams; who looks inside, awakes.
Great dreams of great dreamers are always transcended.
There is an art, or rather a knack to flying. The knack lies in learning how to throw yourself at the ground and miss.
