If there is one thing that is really cheerful in the world, it is cheerfulness. I have noticed it often. And I have noticed that when a man is right down cheerful, he is seldom unhappy for the time being. Such is the nature of man.

Inherited ideas are a curious thing, and interesting to observe and examine.

The Christian Bible is a drug store. It´s contents have remained the same but the medical practice continues. For 1,800 years these changes were slight--scarcely noticeable... The dull and ignorant physician day and night, and all the days and all the nights, drenched his patient with vast and hideous doses of the most repulsive drugs to be found in the store´s stock. He kept him religion sick for eighteen centuries, and allowed him not a well day during all that time.

One must travel, to learn. Every day, now, old Scriptural phrases that never possessed any significance for me before, take to themselves a meaning.

Never argue with stupid people, they will drag you down to their level and then beat you with experience.

Every man feels that his experience is unlike that of anybody else and therefore he should write it down-- he finds also that everybody else has thought and felt on some points precisely as he has done, and therefore he should write it down.

Do good when you can, and charge when you think they will stand it.
