No theory about our bodies as mere objects of observation and calculation (as distinct from partners in communicative interaction, assumed to be free) can comprehend human nature.

Allen W. Wood

Observation and theory get on best when they are mixed together, both helping one another in the pursuit of truth. It is a good rule not to put overmuch confidence in a theory until it has been confirmed by observation. I hope I shall not shock the experimental physicists too much if I add that it is also a good rule not to put overmuch confidence in the observational results that are put forward until they have been confirmed by theory.

Arthur Eddington

If you can't think of an observation that could disprove a theory, that theory simply isn't scientific.

Jerry A. Coyne

We are afraid that Heaven is a bribe, and that if we make it our goal we shall no longer be disinterested. It is not so. Heaven offers nothing that the mercenary soul can desire. It is safe to tell the pure in heart that they shall see God, for only the pure in heart want to. There are rewards that do not sully motives. A man's love for a woman is not mercenary because he wants to marry her, nor his love for poetry mercenary because he wants to read it, nor his love of exercise less disinterested because he wants to run and leap and walk. Love, by definition, seeks to enjoy its object.

C. S. Lewis

Truthful movements spontaneously attract to themselves all manner of pure and disinterested help.

Mahatma Gandhi

There's not a single country that actually approaches economics in a pure, free market, capitalist way. I like the free market - but it very much exists only in textbooks. If I had a choice, and we could live in a very pure world, I would be a supporter of the free markets.

Dambisa Moyo

Philosophers are often actively disinterested in what happens between the cup and the lips (after all, that's "non-ideal theory").

Dale Jamieson

Art is a creation of a higher order than a copy of nature which is governed by chance.... By the elimination of all muddy colors, by the exclusive use of optical mixture of pure colors, by a methodical divisionism and a strict observation of the scientific theory of colors, the neo-impressionists insures a maximum of luminosity, of color intensity, and of harmony- a result that has never yet been obtained.

Paul Signac

Theory can blind observation.

Carol Gilligan

The scientific observer of the realm of nature is in a sense naturally and inevitably disinterested. At least, nothing in the natural scene can arouse his bias. Furthermore, he stands completely outside of the natural so that his mind, whatever his limitations, approximates pure mind. The observer of the realm of history cannot be disinterested in the same way, for two reasons: first, he must look at history from some locus in history; secondly, he is to a certain degree engaged in its ideological conflicts.

Reinhold Niebuhr

Observation always involves theory.

Edwin Powell Hubble

The theory of evolution by natural selection is an ecological theory-founded on ecological observation by perhaps the greatest of all ecologists. It has been adopted by and brought up by the science of genetics, and ecologists, being modest people, are apt to forget their distinguished parenthood.

John L. Harper

It is man's pretence that because he has choice he is free. Freedom is pure observation without direction, without fear of punishment and reward. Freedom is without motive; freedom is not at the end of the evolution of man but lies in the first step of his existence.
