“It’s easier to be original and foolish than original and wise.”

Indeed in general I hold that there is nothing truer than happiness, and nothing happier and sweeter than truth.

To love is to place happiness in the heart of another.

It is necessary to believe that the mixture of evil has produced the greatest possible good: otherwise the evil would not have been permitted.

The present is saturated with the past and pregnant with the future.

What is is what must be.

Justice is charity in accordance with wisdom.

To love is to be delighted by the happiness of someone, or to experience pleasure upon the happiness of another. I define this as true love.

I hold that it is only when we can prove everything we assert that we understand perfectly the thing under consideration.

I do not conceive of any reality at all as without genuine unity.

Nature does not make leaps.

Taking mathematics from the beginning of the world to the time when Newton lived, what he had done was much the better half.

Nothing is necessitated whose opposite is possible.

Every substance is as a world apart, independent of everything else except God.

We never have a full demonstration, although there is always an underlying reason for the truth, even if it is only perfectly understood by God, who alone penetrated the infinite series in one stroke of the mind.

The present is big with the future, the future might be read in the past, the distant is expressed in the near.

Nothing is more important than to see the sources of invention which are, in my opinion more interesting than the inventions themselves.

If I had to choose a religion, the sun as the universal giver of life would be my god.

Because complexity inhibits flexibility, early choices are especially crucial.

I am in charge of my own spaceship. It’s my up, my down. I could choose to see this situation as a setback or a starting point.

The choice, as he saw it, was this: You give up or you work for change. What’s better for us? Barack called to the people gathered in the room. Do we settle for the world as it is, or do we work for the world as it should be?

Early in life I had to choose between honest arrogance and hypocritical humility. I chose honest arrogance and have seen no occasion to change.

Early in my career, I had to choose between an honest arrogance and a hypercritical humility… I deliberately choose an honest arrogance, and I’ve never been sorry.

Perhaps its inevitable, perhaps one has to choose between being nothing at all and impersonating what one is.

You find ways to adapt. If you’re in it forever, there’s really no choice.
