True religion is real living; living with all one's soul, with all one's goodness and righteousness.

We should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality.

We still do not know one thousandth of one percent of what nature has revealed to us.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

My religion consists of a humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind.
