Logics Quotes
It lies deep in our habits, confirmed by all manner of educational and other arrangements for several centuries back, to consider human talent as best of all evincing itself by the faculty of eloquent speech. Our earliest schoolmasters teach us, as the one gift of culture they have, the art of spelling and pronouncing, the rules of correct speech; rhetorics, logics follow, sublime mysteries of grammar, whereby we may not only speak but write. And onward to the last of our schoolmasters in the highest university, it is still intrinsically grammar, under various figures grammar. To speak in various languages, on various things, but on all of them to speak, and appropriately deliver ourselves by tongue or pen,-this is the sublime goal towards which all manner of beneficent preceptors and learned professors, from the lowest hornbook upwards, are continually urging and guiding us.
Thomas Carlyle
I expect that mathematicians have classified such fuzzy logics. Certainly they have been much used by physicists. But is there not something to be said for the approach of Euclid? Even now that we know that Euclidean geometry is (in some sense) not quite true? Is it not good to know what follows from what, even if it is not necessarily FAPP? Suppose for example that quantum mechanics were found to resist precise formulation. Suppose that when formulation beyond FAPP was attempted, we find an unmovable finger obstinately pointing outside the subject, to the mind of the observer, to the Hindu scriptures, to God, or even only Gravitation? Would that not be very, very interesting?
John Stewart Bell
"A frequent source of misunderstanding has to do with the interpretation of fuzzy logic. The problem is that the term fuzzy logic has two different meanings. More specifically, in a narrow sense, fuzzy logic, FLn, is a logical system which may be viewed as an extension and generalization of classical multivalued logics. But in a wider sense, fuzzy logic, FLw is almost synonymous with the theory of fuzzy sets. In this context, what is important to recognize is that: (a) FLw is much broader than FLn and subsumes FLn as one of its branches; (b) the agenda of FLn is very different from the agendas of classical multivalued logics; and (c) at this juncture, the term fuzzy logic is usually used in its wide rather than narrow sense, effectively equating fuzzy logic with FLw.

Is it possible this triviality is a code of some sort? the Brain wondered. But how could it be ... unless there's more to these emotional inconsequentials and this talk of a God than appears on the surface?
The Brain had begun its career in logics as a pragmatic atheist. Now doubts began to creep into its computations, and it classified doubt as an emotion.

The total subject of mathematics is clearly too broad for any one of us. I do not think that any mathematician since Gauss has covered it fully and uniformly, even Hilbert did not, and all of us are of considerably lesser width (quite apart from the question of depth) than Hilbert. It would therefore, be quite unrealistic not to admit, that any address I could possibly give would not be biased towards some areas in mathematics in which I have had some experience, to the detriment of others which may be equally or more important. To be specific, I could not avoid a bias towards those parts of analysis, logics, and certain border areas of the applications of mathematics to other sciences in which I have worked. If your Committee feels that an address which is affected by such imperfections still fits into the program of the Congress, and if the very generous confidence in my ability to deliver continues, I shall be glad to undertake it.
