Henry Ward Beecher

You might just as well read the Bible to a herd of buffaloes as to those fellows ... but they have a supreme respect for the logic ... embodied in Sharp's rifles .

Referring to slaveholders in Kansas:. the then modern weapon, the Sharp, breech-loading rifle

Edward Hungerford

The profuseness of the Arabian learning, the multiplicity of the departments into which it entered, its zeal, the enormous proportions of the resulting literature, the vast libraries, the schools, the lecture rooms with their thousands of students, the universities, the institutions devoted to special sciences, the observatories and laboratories so royally equipped, the schools of logic and grammar, the whole attractive republic of letters, in which princes mingled with the sons of tradesmen or mechanics, while court favorites vied with impoverished authors for the honors of literature, all the ardor of a great intellectual movement passing before our eyes under Oriental guise, dispose the mind to enthusiastic judgments.

During this period—especially the first 500 years, the Islamic world was far ahead of the Christian intellectually and culturally. A university in Bagdad actually had women students as well as men. Ironically, the Muslims studied and preserved the ancient Greek and Roman science and literature while the West slipped into the Dark Ages. The Muslims developed science and the arts to new heights. However, around 1100 a religious orthodoxy began to take hold that saw new innovation of any kind as blasphemous. Intellectually, Islamic society began to decline while at the same time the Christian world was emerging from the dark ages. After the Protestant reformation, Christendom intellectually began to thrive while Islam continued in its anti-intellectual and intolerant mode which still prevents most Muslim nations from modernizing, Note that there was American intellectual interest in Islam towards the end if the 19th century,

Martin Luther

The devil's bride, Reason, that pretty whore, comes in and thinks she's wise, and what she says, what she thinks, is from the Holy Spirit, who can help us, then? Not judges, not doctors, no king or emperor, because reason is the Devil's greatest whore.

Robert Thomson

Editing is agonizing, fretting over facts; it’s not virtue-signaling or confusing the ephemeral with the eternal. Unless we can tell the difference between the meaningful and the meaningless, the material and the immaterial, we will be lost in illogic.

David C. Krakauer

Stupidity is not what remains when intelligence is subtracted, it is an active mechanism with its own logic, its own dynamics, and a capacity for unbounded growth.

Stephen Cole Kleene

For example, the philosophers who were interested in logic were probably rather logical for mathematicians. But the ASL got us together, so we could talk to each other and publish in the same journal.

Mark Twain

… the thug is aware that loudness convinces 60 persons where reasoning convinces but one..

Samuel Langhorne Clemens, 1835-1910. Actually, it is loudness and repetition that are the two most persuasive aspects of oratory.

Richard P. Feynman

Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?

This is a modern summary of the philosophy of Benedict Spinoza who developed the modern philosophical foundation of science and scientific thinking. When the authorities are clerics and religious leaders, their authority gets undermined which is why the Jews, Christians, and Muslims all excommunicated Spinoza. For the scientists, they themselves are to be rejected as determiners of knowledge and truth so they tend to do poorly in political disputes because the good scientists would never assert a belief that the politicians should listen to them just because they are great scientists and they “know.” It is the ideologues and junk scientists who are sure of their testimony and can advise with certainty.

Mustafa Kemal Ataturk

Religion is an important institution. A nation without religion cannot survive. Yet it is also very important to note that religion is a link between Allah and the individual believer. The brokerage of the pious cannot be permitted. Those who use religion for their own benefit are detestable. We are against such a situation and will not allow it. Those who use religion in such a manner have fooled our people; it is against just such people that we have fought and will continue to fight. Know that whatever conforms to reason, logic, and the advantages and needs of our people conforms equally to Islam. If our religion did not conform to reason and logic, it would not be the perfect religion, the final religion.

Christopher Hitchens

What can be asserted without proof can be dismissed without proof

Robert M. Pirsig

Definitions are the foundation of reason. You can't reason without them.

Carl Jung

The word 'belief' is a difficult thing for me. I don't believe. I must have a reason for a certain hypothesis. Either I know a thing, and then I know it - I don't need to believe it.

Monte Melkonian

While many of us feel a strong emotional attachment to our homeland, we should not allow emotions to deter us from speaking of things the way they really are. It should be remembered that this very surrender to emotion has led to insane and counterproductive atrocities on the scale of the Ankara and Istanbul suicide assaults, as well as the Orly bombing and the Lisbon disaster. By surrendering to emotions we enable the A.R.F. and slogans like "Hagop Hagopian" to lead thousands of well-intentioned patriots down a path which does not lead to Armenia, and to sacrifice the lives of young fighters in campaigns which directly contradict the interests of the Armenian people. If we are to achieve even the minimum requirements for Armenian national self-determination, we must approach problems in a serious and sober manner.

Marcus Tullius Cicero

The wise are instructed by reason; ordinary minds by experience; the stupid, by necessity; and brutes by instinct.

Willard Van Orman Quine

Logic is an old subject, and since 1879 it has been a great one.

Jean de la Bruyere

Logic is the art of making truth prevail.

Carl Sagan

Absence of evidence is not evidence of absence.

Oliver Goldsmith

Logicians have but ill defined As rational the human mind; Reason, they say, belongs to man, But let them prove it if they can.

C. S. Lewis

Omnipotence means power to do all that is intrinsically possible, not to do the intrinsically impossible. You may attribute miracles to Him, but not nonsense.

Thomas Hobbes

Reason is the Soul of the Law.

Martin Luther

Reason is the greatest enemy that faith has: it never comes to the aid of spiritual things, but--more frequently than not --struggles against the divine Word, treating with contempt all that emanates from God.

The anti-intellectualism of many Protestant sects has its roots in this view of Martin Luther’s. The notion of reason as practiced by scientists as a hindrance to religion is not a new notion. Religious leaders have been trying to silence and discredit philosophers and scientists as long as there has been religion. Socrates was killed long before Christianity.

Ayn Rand

There are only two means by which men can deal with one another: guns or logic. Force or persuasion. Those who know that they cannot win by means of logic, have always resorted to guns.

Elbert Hubbard

Life is a paradox. Every truth has its counterpart which contradicts it; and every philosopher supplies the logic his own undoing.

Mark Twain

Arguments have no chance against petrified training; they wear it as little as the waves wear a cliff.

Samuel Langhorne Clemens, 1835-1910

Voltaire

Common sense is not so common.
