Quotes About Logic

The difference between prose logic and poetic thought is simple. The logician uses words as a builder uses bricks, for the unemotional deadness of his academic prose; and is always coining newer, deader words with a natural preference for Greek formations.

Poetry at its purest is, indeed, a defiance of logic.

If pressed to supplement Tweedledee's ostensive definition of logic with a discursive definition of the same subject, I would say that logic is the systematic study of the logical truths.

The principles of logic and mathematics are true simply because we never allow them to be anything else. And the reason for this is that we cannot abandon them without contradicting ourselves, without sinning against the rules which govern the use of language, and so making our utterances self-stultifying.

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.

As far as I know, the question of whether and how it could be strategically or morally justified was never the subject of open debate in Germany after 1945, no doubt mainly because a nation which had murdered and worked to death millions of people in its camps could hardly call on the victorious powers to explain the military and political logic that dictated the destruction of the German cities.

Control of thought is more important for governments that are free and popular than for despotic and military states. The logic is straightforward: a despotic state can control its domestic enemies by force, but as the state loses this weapon, other devices are required to prevent the ignorant masses from interfering with public affairs, which are none of their business… the public are to be observers, not participants, consumers of ideology as well as products.

Just between you and me, shouldn’t the World Bank be encouraging MORE migration of the dirty industries to the LDCs [Less Developed Countries]?... I think the economic logic behind dumping a load of toxic waste in the lowest wage country is impeccable and we should face up to that... I’ve always though that under-populated countries in Africa are vastly UNDER-polluted, their air quality is probably vastly inefficiently low compared to Los Angeles or Mexico City.

I perceive the world in fragments. It is somewhat like being on a very fast train and getting glimpses of things in strange scales as you pass by. A person can be very, very tiny. And a billboard can make a person very large. You see the corner of a house or you see a bird fly by, and it's all fragmented. Somehow, in painting I try to make some logic out of the world that has been given to me in chaos. I have a very pretentious idea that I want to make life, I want to make sense out of it. The fact that I am doomed to failure - that doesn't deter me in the least.
