Logical Truth - Logical Truth and Rules of Inference

Famous quotes containing the words logical, truth, rules and/or inference:

“Nature’s law says that the strong must prevent the weak from living, but only in a newspaper article or textbook can this be packaged into a comprehensible thought. In the soup of everyday life, in the mixture of minutia from which human relations are woven, it is not a law. It is a logical incongruity when both strong and weak fall victim to their mutual relations, unconsciously subservient to some unknown guiding power that stands outside of life, irrelevant to man.”
—Anton Pavlovich Chekhov (1860–1904)

“The thinking person has the strange characteristic to like to create a fantasy in the place of the unsolved problem, a fantasy that stays with the person even when the problem has been solved and truth made its appearance.”
—Johann Wolfgang Von Goethe (1749–1832)

“For rhetoric, he could not ope
His mouth, but out there flew a trope;
And when he happen’d to break off
I’ th’ middle of his speech, or cough,
H’ had hard words ready to show why,
And tell what rules he did it by;”
—Samuel Butler (1612–1680)

“I have heard that whoever loves is in no condition old. I have heard that whenever the name of man is spoken, the doctrine of immortality is announced; it cleaves to his constitution. The mode of it baffles our wit, and no whisper comes to us from the other side. But the inference from the working of intellect, hiving knowledge, hiving skill,—at the end of life just ready to be born,—affirms the inspirations of affection and of the moral sentiment.”
—Ralph Waldo Emerson (1803–1882)
