I believe in the immortality of the soul because I have within me immortal longings.
No pessimist ever discovered the secrets of the stars.
A man can't make a place for himself in the sun if he keeps taking refuge under the family tree.
Use your eyes as if tomorrow you would become blind.
Happiness is the final and perfect fruit of obedience to the laws of life.
Although the world is full of suffering, it is full also of the overcoming of it. My optimism, then, does not rest on the absence of evil, but on a glad belief in the preponderance of good and a willing effort always to cooperate with the good, that it may prevail.
