My religious faith remains in possession of the field only after prolonged civil war with my naturally skeptical mind.

In the whole story of Jesus Christ, the most important event is the resurrection.

Real happiness is not dependent on external things.

The principle of happiness should be like the principle of virtue: it should not be dependent of things, but be a part of personality [and character].

Life, with all it's sorrows, cares, perplexities and heart-breaks, is more interesting than bovine placidity, hence more desirable. The more interesting it is, the happier it is.

I find daily life not always joyous, but always interesting. I have some sad days and nights, but none that are dull. As I advance deeper into the vale of years, I live with constantly increasing gusto and excitement. I am sure it all means something; in the last analysis, I am an optimist because I believe in God. Those who have no faith are quite naturally pessimists and I do not blame them.

The happiest people in this world are those who have the most interesting thoughts.
