Logic Quotes

“it was the United States which first established general suffrage for men upon the two principles that 'taxation without representation is tyranny' and that governments to be just should 'derive their consent from the governed.' The unanswerable logic of these two principles is responsible for the extension of suffrage to men and women the world over. In the United States, however, women are still taxed without 'representation' and still live under a government to which they have given no 'consent.”

“The concept of absolute, hence (or whence) springs, in the moral field, the moral laws or norms, represent, in the field of knowledge, the principle of identity, which is the fundamental law of the thought; norms of logic springs from it, that govern the thought (or mind) in the field of science." ("Le concept de l'absolu, d'où découlent, dans le domaine moral, les lois ou normes morales, constitue, le principe d'identité, qui est la loi fondamentale de la pensée; il en découle les normes logiques qui régissent la pensée dans le domaine de la science.")”

“The logic of all this seems to be that it is all right for young people in a democracy to learn about any civilization or social theory that is not dangerous, but that they should remain entirely ignorant of any civilization or social theory that might be dangerous on the ground that what you don't know can't hurt you ... a complete denial of the democratic principle that the general diffusion of knowledge and learning through the community is essential to the preservation of free government.”

“The conclusion of intelligent design flows naturally from the data itself - not from sacred books or sectarian beliefs. Inferring that biochemical systems were designed by an intelligent agent is a humdrum process that requires no new principles of logic or science. It comes simply from the hard work that biochemistry has done over the past forty years, combined with consideration of the way in which we reach conclusions of design every day.”

“I took biology in high school and didn't like it at all. It was focused on memorization. ... I didn't appreciate that biology also had principles and logic ... [rather than dealing with a] messy thing called life. It just wasn't organized, and I wanted to stick with the nice pristine sciences of chemistry and physics, where everything made sense. I wish I had learned sooner that biology could be fun as well.”

“Like Molière's M. Jourdain, who spoke prose all his life without knowing it, mathematicians have been reasoning for at least two millennia without being aware of all the principles underlying what they were doing. The real nature of the tools of their craft has become evident only within recent times A renaissance of logical studies in modern times begins with the publication in 1847 of George Boole's The Mathematical Analysis of Logic.”

“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. In other words, the truths of logic and mathematics are analytic propositions or tautologies.”

“The old Catholic church traditions are worth more than all you have said. Here is a principle of logic that most men have no more sense than to adopt. I will illustrate it by an old apple tree. Here jumps off a branch and says, I am the true tree, and you are corrupt. If the whole tree is corrupt, are not its branches corrupt? If the Catholic religion is a false religion, how can any true religion come out of it? If the Catholic church is bad, how can any good thing come out of it?”

“The whole world knows that American TV companies have monopolized Olympic broadcasts and in order to please the fans in their country they do everything they can to keep American viewers interested in what is going on at the hockey rink in Sochi. According to their logic, Americans should always win, no matter what. It was absolutely obvious that [Fyodor] Tyutin's goal yesterday should have been allowed. This was clear to the whole world except the American referee, American TV and those officials with American passports who rule international hockey, grossly neglecting all Olympic principles.”

“From the point of view of logic, my report on 'Exclusion principle and quantum mechanics' has no conclusion. I believe that it will only be possible to write the conclusion if a theory will be established which will determine the value of the fine structure constant and will thus explain the atomistic structure of electricity, which is such an essential quality of all atomic sources of electric fields actually occurring in nature.”

“Most people in the world believe that if there is a God, you relate to God by being good. Most religions are based on that principle, though there are a million different variations on it...But they all have the same logic: If I perform, if I obey, I’m accepted. The gospel of Jesus is not only different from that but diametrically opposed to it: I’m fully accepted in Jesus Christ, and therefore I obey.”
