• If I could prove by logic that you would die in five minutes, I should be sorry you were going to die, but my sorrow would be very much mitigated by pleasure in the proof.

  G. H. Hardy

  Sorry, Sorrow, Would Be

• Analytic It is clear that the definition of "logic" or "mathematics" must be sought by trying to give a new definition of the old notion of "analytic" propositions.

• Formality Thus the absence of all mention of particular things or properties in logic or pure mathematics is a necessary result of the fact that this study is, as we say, "purely formal".

• What would mathematics have amounted to without the imagination of its devotees-its giants and their followers? There never was a discovery made without the urge of imagination-of imagination which broke the roadway through the forest in order that cold logic might follow.

• The theoretician believes in logic and believes that he despises dreams, intuition, and poetry. He does not recognize that these three fairies have only disguised themselves in order to dazzle him.... He does not know that he owes his greatest discoveries to them.

• If such external influences are intrinsic to religion, then logic and scientific thought dictate that there must be a mechanism by which this influence is transmitted. A religious or spiritual belief that involves an invisible undetectable force that nonetheless influences human actions and behavior or that of the world itself produces a situation in which a believer has no choice but to have faith and abandon logic--or simply not care.

• The rejection of all abstract formalism. Materialism reminds every science of its real source: the world men transform. No science can, whether in its history or its object, grasp its own origins within itself or constitute itself as a closed world, exhaustively defined by internal rules. Materialism refers every science and every activity to the reality they depend on, even if this dependence is masked by a great many abstract mediations: mathematics as well as logic, aesthetics as well as ethics and politics.

• Based on the considerations of history, ancient history, and international axioms, the logic of following up a citizen with his shadow for the purpose of the demarcation of political frontiers of any state has been discounted for international conventions. For example the Arabs cannot ask Spain just because they were there some time in the past nor can they ask for any other area outside the frontiers of the Arab homeland

• Kurt Godel's achievement in modern logic is singular and monumental - indeed it is more than a monument, it is a landmark which will remain visible far in space and time. ... The subject of logic has certainly completely changed its nature and possibilities with Godel's achievement.

• ... We in the USA have been depending on prayers, pleading, and self-abasement to a deity to bring us magical advantages, and have been encouraged to attribute our prosperity and general success among nations, to that sort of action. In my opinion, hard work and dedication to logic and reason ought to be recognized as the reasons for our achievements, not appeals to a mythical friend-in-the-sky. We got where we are in spite of, not because of, those incantations.

  James Randi

• The four points of the compass be logic, knowledge, wisdom and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three. I may submit to the unknown, but never to the unknowable. The man who bows in that final direction is either a saint or a fool. I have no use for either.

• Chess is a unique battlefield for human minds and computers - human intuition, our creativity, fantasy, our logic, versus the brute force of calculation and a very small portion of accumulated knowledge infused by other human beings. So in chess we can compare these two incompatible things and probably make projections into our future. Is there danger that the human mind will be overshadowed by the power of computers, or we can still survive?

• I've never wanted to be a witch, but an alchemist, now that's a different matter. To invent this wizard world, I've learned a ridiculous amount about alchemy. Perhaps much of it I'll never use in the books, but I have to know in detail what magic can and cannot do in order to set the parameters and establish the stories' internal logic.

• Right up till the 1980s, SF envisioned giant mainframe computers that ran everything remotely, that ingested huge amounts of information and regurgitated it in startling ways, and that behaved (or were programmed to behave) very much like human beings... Now we have 14-year-olds with more computing power on their desktops than existed in the entire world in 1960. But computers in fiction are still behaving in much the same way as they did in the Sixties. That's because in fiction [artificial intelligence] has to follow the laws of dramatic logic, just like human characters.

• There will have to be rigid and iron discipline before we achieve anything great and enduring, and that discipline will not come by mere academic argument and appeal to reason and logic. Discipline is learnt in the school of adversity.

• O poor, unthinking human heart! Error will not go away, logic and reason are slow to penetrate.We cling with both arms to false hope, refusing to believe in the weightiest proofs against it, embracing it with all our strength. In the end it escapes, ripping our veins and draining our heart's blood; until, regaining consciousness, we rush to fall into snares of delusion all over again
