Auguste Comte Quotes

When we human beings hypothesize that a law of nature holds - even temporarily or situationally - we are creating an idea, but we are also making a hypothesis about how nature behaves, whose truth or usefulness has nothing to do with what we know or believe.

All good intellects have repeated, since Bacon's time, that there can be no real knowledge but which is based on observed facts.

Natural objects, for example, must be experienced before any theorizing about them can occur.

All good intellects have repeated, since Bacon's time, that there can be no real knowledge but that which is based on observed facts. This is incontestable, in our present advanced stage; but, if we look back to the primitive stage of human knowledge, we shall see that it must have been otherwise

Real science exists, then, only from the moment when a phenomenon is accurately defined as to its nature and rigorously determined in relation to its material conditions, that is, when its law is known. Before that, we have only groping and empiricism.

General Systems Theory is a name which has come into use to describe a level of theoretical model-building which lies somewhere between the highly generalized constructions of pure mathematics and the specific theories of the specialized disciplines. Mathematics attempts to organize highly general relationships into a coherent system, a system however which does not have any necessary connections with the "real" world around us. It studies all thinkable relationships abstracted from any concrete situation or body of empirical knowledge.

I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed.

Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.

Some physicists describe gravity in terms of ten dimensions all curled up. But those aren't real words-just placeholders, used to refer to parts of abstract equations.

Truth does not demand belief. Scientists do not join hands every Sunday, singing, 'Yes, gravity is real! I will have faith!'

The role of science is to be systematic, to be accurate, to be orderly, but it certainly is not to imply that the aggregated, successful hypotheses of the past have the kind of truth that goes into a number system.

Isolated facts and experiments have in themselves no value, however great their number may be. They only become valuable in a theoretical or practical point of view when they make us acquainted with the law of a series of uniformly recurring phenomena, or, it may be, only give a negative result showing an incompleteness in our knowledge of such a law, till then held to be perfect.

It is a very long and very difficult road from a fact to a conclusion. But it is a million times longer from a theory to a fact.

We call the one side [of humanity] religion, and we call the other science. Religion is always right. ... Science is always wrong; it is the very artifice of men. Science can never solve one problem without raising ten more problems.

In order that the facts obtained by observation and experiment may be capable of being used in furtherance of our exact and solid knowledge, they must be apprehended and analysed according to some Conceptions which, applied for this purpose, give distinct and definite results, such as can be steadily taken hold of and reasoned from.

The aim ... is to provide a clear and rigorous basis for determining when a causal ordering can be said to hold between two variables or groups of variables in a model . . . . The concepts refer to a model-a system of equations-and not to the 'real' world the model purports to describe.

Contrary to what I once thought, scientific progress did not consist simply in observing, in accurately formulating experimental facts and drawing up a theory from them. It began with the invention of a possible world, or a fragment thereof, which was then compared by experimentation with the real world. And it was this constant dialogue between imagination and experiment that allowed one to form an increasingly fine-grained conception of what is called reality.

Think of a hypothesis as a card. A theory is a house made of hypotheses.

Facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome.

A few drops of science will often disinfect an entire barrel full of ignorance and prejudice.

These are people from everywhere, from Lawrence Livermore and JPL and Sandia National Labs, the FBI, all over the place, real scientists who see what we're doing, and they consistently thank us. "I agree your results aren't always right," they'll say, "but your methods are clearly showing that science is a re-creative process, and it's an interesting process because it's messy, and no other shows show that."

Scientists do not join hands every Sunday and sing "Yes gravity is real! I know gravity is real! I will have faith! I believe in my heart that what goes up, up, up must come down, down, down. Amen!" If they did, we would think they were pretty insecure about the concept.

Theory can leave questions unanswered, but practice has to come up with something.

Science is the knowledge of Consequences, and dependence of one fact upon another: by which, out of that we can presently do, we know how to do something else when we will, or the like, another time

But the real glory of science is that we can find a way of thinking such that the law is evident.
