A Quote by Robert A. Heinlein
Analogy is even slipperier than logic.

... one of the main functions of an analogy or model is to suggest extensions of the theory by considering extensions of the analogy, since more is known about the analogy than is known about the subject matter of the theory itself ... A collection of observable concepts in a purely formal hypothesis suggesting no analogy with anything would consequently not suggest either any directions for its own development.
I made a lot of exits through side doors, down fire escapes or over rooftops. I abandoned more wardrobes in the course of five years than most men acquire in a lifetime. I was slipperier than a buttered escargot.
I think it's important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. [With analogy] we are doing this because it's like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.
The want of logic annoys. Too much logic bores. Life eludes logic, and everything that logic alone constructs remains artificial and forced.
Catastrophe Theory is-quite likely-the first coherent attempt (since Aristotelian logic) to give a theory on analogy. When narrow-minded scientists object to Catastrophe Theory that it gives no more than analogies, or metaphors, they do not realise that they are stating the proper aim of Catastrophe Theory, which is to classify all possible types of analogous situations.
To reason from analogy is often dangerous, but to illustrate by a fanciful analogy is sometimes a means by which we light an idea, as it were, into the understanding of another.
Poems - crystallizations of the universal play of analogy, transparent objects which, as they reproduce the mechanism and the rotary motion of analogy, are waterspouts of new analogies.
First, in your sermons, use your logic, and then your rhetoric; Rhetoric without logic, is like a tree with leaves and blossoms, but no root; yet more are taken with rhetoric than logic, because they are caught with fine expressions when they understand not reason.
Logic is justly considered the basis of all other sciences, even if only for the reason that in every argument we employ concepts taken from the field of logic, and that ever correct inference proceeds in accordance with its laws.
I enjoy logic and logic puzzles. And filmmaking is one fun logic puzzle that you gotta win.
It is possible--indeed possible even according to the old conception of logic--to give in advance a description of all 'true' logical propositions. Hence there can never be surprises in logic.
Logic is invincible, because in order to combat logic it is necessary to use logic.
The aim of all commentary on art now should be to make works of art - and, by analogy, our own experience - more, rather than less, real to us. The function of criticism should be to show how it is what it is, even that it is what it is, rather than to show what it means.
Crime is common. Logic is rare. Therefore it is upon the logic rather than upon the crime that you should dwell.
Poincaré was a vigorous opponent of the theory that all mathematics can be rewritten in terms of the most elementary notions of classical logic; something more than logic, he believed, makes mathematics what it is.
Why should ANYTHING go right; even observation and deduction? Why should not good logic be as misleading as bad logic? They are both movements in the brain of a bewildered ape?
