Art and science have their meeting point in method.

False facts are highly injurious to the progress of science, for they often endure long but false views, if supported by some evidence, do little harm, for everyone takes a salutory pleasure in proving their falseness.

Fashion is the science of appearances, and it inspires one with the desire to seem rather than to be.

Human science is an uncertain guess.

I do not understand why some would call me an economic oracle. Although I correctly foretasted key economic events in the past 10 years, the truth is that any economic forecasting model can become useless with the change of just one variable. And if we learned anything from experience, the only constant in markets is change. The first rule of economic forecasting is to understand that it is a science of probability not a science of certainty.

If we lose our capacity to write about our emotions, we might as well attach to science.

Medicine is a science of uncertainty and an art of probability.

My people are going to learn the principles of democracy the dictates of truth and the teachings of science. Superstition must go. Let them worship as they will, every man can follow his own conscience provided it does not interfere with sane reason or bid him act against the liberty of his fellow men.

Natural science will in time incorporate into itself the science of man, just as the science of man will incorporate into itself natural science: there will be one science.

Nature is itself a great science; it already exists. One needs the tools for that, to see how it is possible.

No other theory is adequate to explain or comprehend the Declaration of Independence. It is the product of the spiritual insight of the people. We live in an age of science and of abounding accumulation of material things. These did not create our Declaration. Our Declaration created them. The things of the spirit come first. Unless we cling to that, all our material prosperity, overwhelming though it may appear, will turn to a barren sceptre in our grasp. If we are to maintain the great heritage which has been bequeathed to us, we must be like minded as the fathers who created it. We must not sink into a pagan materialism. We must cultivate the reverence which they had for the things that are holy. We must follow the spiritual and moral leadership which they showed. We must keep replenished, that they may glow with a more compelling flame, the altar fires before which they worshiped.

Perfect as the wing of a bird may be, it will never enable the bird to fly if unsupported by the air. Facts are the air of science. Without them a man of science can never rise.

Science is a differential equation. Religion is a boundary condition.

Religion belongs to the realm that is inviolable before the law of causation and therefore closed to science.

Science is nothing but developed perception, interpreted intent, common sense rounded out and minutely articulated.
