Heuristic Quotes
If there was some central theme beneath the (more Irish than Greek) stew of intuitions about the nature of human existence – and of fiction – it is perhaps in the alternative title, whose rejection I still sometimes regret: The Godgame. I did intend Conchis to exhibit a series of masks representing human notions of God, from the supernatural to the jargon-ridden scientific, that is, a series of human illusions about something that does not exist in fact, absolute knowledge and absolute power. The destruction of such illusions seems to me still an eminently humanist aim; and I wish there were some super-Conchis who could put the Arabs and the Israelis, or the Ulster Catholics and Protestants, through the same heuristic mill as Nicholas.
John Fowles
The physicist needs a facility in looking at problems from several points of view. The exact analysis of real physical problems is usually quite complicated, and any particular physical situation may be too complicated to analyze directly by solving the differential equation. But one can still get a very good idea of the behavior of a system if one has some feel for the character of the solution in different circumstances. Ideas such as the field lines, capacitance, resistance, and inductance are, for such purposes, very useful. ... On the other hand, none of the heuristic models, such as field lines, is really adequate and accurate for all situations. There is only one precise way of presenting the laws, and that is by means of differential equations. They have the advantage of being fundamental and, so far as we know, precise. If you have learned the differential equations you can always go back to them. There is nothing to unlearn.
Richard Feynman
![A child learning his [her] mother tongue is learning how to name; he [she] is building up a meaning potential in respect of a limited number of social functions. These functions [instrumental, regulatory, interactional, personal, heuristic, and imaginative] constitute the semiotic environment of a very small child, and may be thought of as universals of human culture.

Intelligence has two parts, which we shall call the epistemological and the heuristic. The epistemological part is the representation of the world in such a form that the solution of problems follows from the facts expressed in the representation. The heuristic part is the mechanism that on the basis of the information solves the problem and decides what to do.

The right way to think about the general problems of metaphysics and epistemology is not to attempt to clear one's own mind of all knowledge and start with 'Cogito ergo sum' and build up from there. Instead, we propose to use all of our knowledge to construct a computer program that knows. The correctness of our philosophical system will be tested by numerous comparisons between the beliefs of the program and our own observations and knowledge.
John McCarthy (computer scientist)
I do not see any reason to assume that the heuristic significance of the principle of general relativity is restricted to gravitation and that the rest of physics can be dealt with separately on the basis of special relativity, with the hope that later on the whole may be fitted consistently into a general relativistic scheme. I do not think that such an attitude, although historically understandable, can be objectively justified. The comparative smallness of what we know today as gravitational effects is not a conclusive reason for ignoring the principle of general relativity in theoretical investigations of a fundamental character. In other words, I do not believe that it is justifiable to ask: What would physics look like without gravitation?
Albert Einstein
There's a serious danger that the college education bubble may burst. As more and more people get college degrees, which inevitably have to become easier to get in order to increase the amount of graduates beyond its realistic levels, the market will eventually figure out that the degree doesn't mean what it used to. It will become less useful as a heuristic for intelligence and achievement. And college graduates will find themselves with an asset-a degree-whose value is dropping while their debt remains high.
