Logical Consistency Quotes

The criterion of the scientific status of a theory is its falsifiability, or refutability, or testability.

Neither Aristotelian nor Russellian rules give the exact logic of any expression of ordinary language; for ordinary language has no exact logic.

Of course I'm inconsistent! Only logicians and cretins are consistent!

Particularly, the actors, to have analyzed the script in great detail from the point of view of their specific character. So that they have a handle on exactly where the character is in the chronology of things.

In Scientology you discover for yourself what is true for you.

The claim is also sometimes made that science is as arbitrary or irrational as all other claims to knowledge, or that reason itself is an illusion. As Ethan Allen said Those who invalidate reason ought seriously to consider whether they argue against reason with or without reason; if with reason, then they establish the principle that they are labouring to dethrone. If they argue without reason, which they must do, in order to be consistent with themselves, they are out of reach of rational conviction, nor do they deserve a rational argument.

The Libertarians, of whom I'm rather fond, are running Harry Browne. Libertarians are, just as they claim, principled and consistent - they believe in individual liberty. Commendable as they are, and despite their reliability as allies in civil liberties struggles, you may notice that Libertarians sometimes prove that a foolish consistency is the hobgoblin of little minds, and that there is a difference between logic and wisdom.

Like everything metaphysical the harmony between thought and reality is to be found in the grammar of the language.

Knowledge is a continuous fabric, in which ideas are connected to other ideas. Reason-free zones, in which people can assert arbitrary beliefs safe from ordinary standards of evaluation, can only corrupt this fabric, just as a contradiction can corrupt a system of logic, allowing falsehoods to proliferate through it.

One never wants to do anything that's going to break that 'sculpture of the character' that's been done so far, or make anything that's been done so far become illogical in any way, so you always want to try to connect when you're doing a series of films that has a continuous character.

The day may come when we will replace politicians with computers. Judging from some of the reasoning of politicians I've seen over the years, I know I would sooner take the logic of a computer. The machine may suffer the same lack of intelligence as some politicians, but at least there is consistency in its idiocy.

A universe whose only claim to be believed in rests on the validity of inference must not start telling us the inference is invalid.

Mathematics catalogues everything that is not self-contradictory; within that vast inventory, physics is an island of structures rich enough to contain their own beholders.

In inventing a model we may assume what we wish, but should avoid impossibilities.

Rules and particular inferences alike are justified by being brought into agreement with each other. A rule is amended if it yields an inference we are unwilling to accept; an inference is rejected if it violates a rule we are unwilling to amend.

Solipsism may be logically consistent with present Quantum Mechanics, Monism in the sense of Materialism is not.

Careful economic analysis does have one important benefit, which is that it can help kill ideas that are completely logically inconsistent or wildly at variance with the data. This insight covers at least 90 percent of proposed economic policies

The fact is the statements are perfectly consistent, but more importantly, I don't have all the facts.

An axiomatic system establishes a reverberating relationship between what a mathematician assumes (the axioms) and what he or she can derive (the theorems). In the best of circumstances, the relationship is clear enough so that the mathematician can submit his or her reasoning to an informal checklist, passing from step to step with the easy confidence the steps are small enough so that he cannot be embarrassed nor she tripped up.
