“The beginning, middle, and end of the birth, growth, and perfection of whatever we behold is from contraries, by contraries, and to contraries; and whatever contrariety is, there is action and reaction, there is motion, diversity, multitude, and order, there are degrees, succession and vicissitude.”

The fools of the world have been those who have established religions, ceremonies, laws, faith, rule of life.

Time is the father of truth, its mother is our mind.

But I have reasoned deeply, and, speaking as a philosopher, since the soul is not found without body and yet is not body, it may be in one body or in another, and pass from body to body.

There is a single general space, a single vast immensity which we may freely call void: in it are unnumerable globes like this on which we live and grow, this space we declare to be infinite, since neither reason, convenience, sense-perception nor nature assign to it a limit.

Innumerable suns exist; innumerable earths revolve around these suns in a manner similar to the way the seven planets revolve around our sun. Living beings inhabit these worlds.

I need not instruct you of my belief: Time gives all and takes all away ; everything changes but nothing perishes ;

Of the eternal incorporeal substance nothing is changed, is formed or deformed, but there always remains only that thing which cannot be a subject of dissolution, since it is not possible that it be a subject of composition, and therefore, either of itself or by accident, it cannot be said to die.

With luck on your side, you can do without brains.

Truth does not change because it is, or is not, believed by a majority of the people.

I cleave the heavens and soar to the infinite. And while I rise from my own globe to others and penetrate ever further through the eternal field. That which others saw from afar, I leave far behind me.

Our bodily eye findeth never an end, but is vanquished by the immensity of space.

Anything we take in the Universe, because it has in itself that which is All in All, includes in its own way, the entire soul of the world, which is entirely in any part of it.

We delight in one knowable thing, which comprehends all that is knowable; in one apprehensible, which draws together all that can be apprehended; in a single being that includes all, above all in the one which is itself the all.

Maybe you who condemn me are in greater fear than I who am condemned.

It may be you fear more to deliver judgment upon me than I fear judgment.

What can be more stupid than to be in pain about future things and absent ones which at present are not felt?

Temptation, if it is not to conquer, must not fall like a bomb against another bomb of instantaneous moral explosions, but against the strong walls of an impregnable fortress strongly built up, stone by stone, beginning at that distant day when the foundations were first laid.

We begin to realise that the molecular scattering of light in liquids may possess an astronomical significance, in fact contribute in an important degree to the observed albedo of the earth.

The past is but the past of a beginning.

It is difficult to know at what moment love begins; it is less difficult to know that it has begun.

When the child begins to think and to make use of the written language to express his rudimentary thinking, he is ready for elementary work; and this fitness is a question not of age or other incidental circumstance but of mental maturity.

Covetousness is both the beginning and the end of the devil’s alphabet – the first vice in corrupt nature that moves, and the last which dies.

When you are younger you get blamed for crimes you never committed and when you’re older you begin to get credit for virtues you never possessed. It evens itself out.

To fly as fast as thought, you must begin by knowing that you have already arrived.
