Writing is the geometry of the soul.

Plato

To attain knowledge, add things every day. To attain wisdom, remove things every day.

Laozi

The secret of happiness is freedom and the secret of freedom is courage.

Thucydides

Our life is shaped by our mind; we become what we think. Joy follows a pure thought like a shadow that never leaves.

The Buddha (Eknath Easwaran translation)

We shape our buildings; thereafter they shape us.

Winston Churchill

It is a wonderful feeling to recognise the unity of complex phenomena that to direct observation appear to be quite separate things.

Albert Einstein

Truth is one, the sages speak of it by many names.

Joseph Campbell

Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.

Galileo Gallili

All mass is interaction.

Richard Feynman

The more we progress the more we tend to progress. We advance not in arithmetical but in geometrical progression. We draw compound interest on the whole capital of knowledge and virtuewhich has been accumulated since the dawning of time. Some eighty thousand years are supposed to have existed between paleolithic and neolithic man. Yet in all that time he only learned to grind his flint stones instead of chipping them. But within our father’s lives what changes have there not been? The railway and the telegraph, chloroform and applied electricity. Ten years now go further than a thousand then, not so much on account of our finer intellects as because the light we have shows us the way to more. Primeval man stumbled along with peering eyes, and slow, uncertain footsteps. Now we walk briskly towards our unknown goal.

Arthur Conan Doyle

It is better to suffer wrong than to do it, and happier to be sometimes cheated than not to trust.

 Samuel Johnson

All joy or sorrow for the happiness or calamities of others is produced by an act of the imagination, that realizes the event however fictitious, or approximates it however remote, by placing us, for a time, in the condition of him whose fortune we contemplate.

Samuel Johnson

When you have mastered the numbers, you will in fact no longer be reading numbers, any more than you read words when reading a book. You will be reading meanings.

Harold Geneen

The number 2 is a very dangerous number: that is why the dialectic is a dangerous process. Attempts to divide anything into two ought to be regarded with much suspicion.

C.P. Snow

If you don’t want to pay the price of maintaining peace, you will have a lot of war

Jean Chrétien

I am, and ever will be, a white-socks, pocket-protector, nerdy engineer – born under the second law of thermodynamics, steeped in the steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow.

Neil Armstrong

Once we have granted that any physical theory is essentially only a model for the world of experience, we must renounce all hope of finding anything like “the correct theory.” There is nothing which prevents any number of quite distinct models from being in correspondence with experience (i.e., all “correct”), and furthermore no way of ever verifying that any model is completely correct, simply because the totality of all experience is never accessible to us.”

Hugh Everett

The ocean can be yours; why should you stop
Beguiled by dreams of evanescent dew?
The secrets of the sun are yours, but you
Content yourself with motes trapped in beams.

Attar of Nishapur, The Conference of the Birds

. . . it is a fundamental requirement of the scientific viewpoint—the so-called principle of the psycho-physical parallelism—that it must be possible so to describe the extra-physical process of the subjective perception as if it were in reality in the physical world—i.e., to assign to its parts equivalent physical processes in the objective environment, in ordinary space.

J. von Neumann, Mathematical Foundations of Quantum Mechanics. (Translated by R. T. Beyer)

We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information.

Jorge Luis Borges

We may regard the present state of the universe as the effect of the past and the cause of the future. An intellect which at any given moment knew all of the forces that animate nature and the mutual positions of the beings that compose it, if this intellect were vast enough to submit the data to analysis, could condense into a single formula the movement of the greatest bodies of the universe and that of the lightest atom; for such an intellect nothing could be uncertain and the future just like the past would be present before its eyes.

Pierre Simon Laplace, A Philosophical Essay on Probabilities

All stable processes we shall predict. All unstable processes we shall control.

Von Neumann

Imagine how hard physics would be if electrons could think

Murray Gell-Mann, The Quark and the Jaguar by W.H. Freeman

The mental model is fuzzy. It is incomplete. It is imprecisely stated. Furthermore, within one individual, a mental model changes with time and even during the flow of a single conversation. The human mind assembles a few relationships to fit the context of a discussion. As the subject shifts so does the model. When only a single topic is being discussed, each participant in a conversation employs a different mental model to interpret the subject. Fundamental assumptions differ but are never brought into the open. Goals are different and are left unstated. It is little wonder that compromise takes so long. And it is not surprising that consensus leads to laws and programs that fail in their objectives or produce new difficulties greater than those that have been relieved.

Jay Wright Forrester

If you want to build a ship, don’t drum up the people to gather wood, divide the work, and give orders. Instead, teach them to yearn for the vast and endless sea.

Antoine de Saint-Exupéry

Traditional view of a God creating the universe ex-nihilo means you need to take the current mass-energy content of the universe, 4 x 10^69 Joules, and have expelled it in the time before time existed, one unit of Planck time, or 5.39124 x 10^-44 seconds, coming up with 7 x 10^112 Watts. This would put God, at a bare minimum, as a Type X. [according to Carl Sagan’s derivation of the Kardashev scale]
