What kind of husband would I be if I bet against my own marriage?'I smiled. 'The stupid kind. Didn't you listen to your dad when he told you not to bet against me?

We ought to regard the present state of the universe as the effect of its antecedent state and as the cause of the state that is to follow. An intelligence knowing all the forces acting in nature at a given instant, as well as the momentary positions of all things in the universe, would be able to comprehend in one single formula the motions of the largest bodies as well as the lightest atoms in the world, provided that its intellect were sufficiently powerful to subject all data to analysis; to it nothing would be uncertain, the future as well as the past would be present to its eyes. The perfection that the human mind has been able to give to astronomy affords but a feeble outline of such an intelligence.

Because you're always learning, the chief lesson remains: you still know nothing.

Hope is certainty of the desired want.

The opposite of faith isn’t doubt. The opposite of faith is certainty.

Certainty is the most vivid condition of ignorance and the most necessarycondition for knowledge.

Peaceful disputes are maintained when men sincerely believe that they are morally, logically correct about the issues at hand. It is when neither side is really certain that wars are instigated.

As we watch the process in which the soul becomes thought or speech, we notice that many a time we ease ourselves into convenient clichés that have little of the new insight in them. Once more we are trapped by habits that are the dunghills upon which the creeds feed. It takes vigilance and humble courage to make acts of faith. After all, where faith is weak, there is an abundance of beliefs. With this in mind we may be more humble about our tradition and our sureness, yet also a bit more proud of the holy process in our inner being that keeps teaching and guiding us.

There is no such uncertainty as a sure thing.

Such is true joy’s absolute certainty,Its slow lit fuse that burns holesIn the shabby shroud of death forever.
