The so called unconscious inferences can be traced back to the all-preserving memory, which presents us with parallel experiences and hence already knows the consequences of an action. It is not anticipation of the effects; rather, it is the feeling: identical causes, identical effects . . .

Friedrich Nietzsche

Inferences of Science and Common Sense differ from those of deductive logic and mathematics in a very important respect, namely, when the premises are true and the reasoning correct, the conclusion is only probable.

Bertrand Russell

There are two modes of acquiring knowledge, namely by reasoning and experience. Reasoning draws a conclusion and makes us grant the conclusion, but does not make the conclusion certain, nor does it remove doubt so that the mind may rest on the intuition of truth, unless the mind discovers it by the path of experience.

Roger Bacon

Across a range of inferences involving not just language but mathematics, logic problems, and spatial reasoning, sleep has been shown to enhance the formation and understanding of abstract relations, so much so that people often wake having solved a problem that was unsolvable the night before.

Daniel Levitin

If ... the past may be no Rule for the future, all Experience becomes useless and can give rise to no Inferences or Conclusions.

David Hume

Man is made for science; he reasons from effects to causes, and from causes to effects; but he does not always reason without error. In reasoning, therefore, from appearances which are particular, care must be taken how we generalize; we should be cautious not to attribute to nature, laws which may perhaps be only of our own invention.

James Hutton

People's conceptions about themselves and the nature of things are developed and verified through four different processes: direct experience of the effects produced by their actions, vicarious experience of the effects produced by somebody else's actions, judgments voiced by others, and derivation of further knowledge from what they already know by using rules of inference

Albert Bandura

It is not really difficult to construct a series of inferences, each dependent upon its predecessor and each simple in itself. If, after doing so, one simply knocks out all the central inferences and presents one's audience with the starting-point and the conclusion, one may produce a startling, though perhaps a meretricious, effect.

Arthur Conan Doyle

Women never reason, or, if they do, they either draw correct inferences from wrong premises, or wrong inferences from correct premises; and they always poke the fire from the top.

Richard Whately

Culture has never the translucidity of custom; it abhors all simplification. In its essence it is opposed to custom, for custom is always the deterioration of culture.

Frantz Fanon

The deep paradox uncovered by AI research: the only way to deal efficiently with very complex problems is to move away from pure logic.... Most of the time, reaching the right decision requires little reasoning.... Expert systems are, thus, not about reasoning: they are about knowing.... Reasoning takes time, so we try to do it as seldom as possible. Instead we store the results of our reasoning for later reference.

Daniel Crevier

Experience is the mother of custom.

Henry Ward Beecher

No one can explain how the notes of a Mozart melody, or the folds of a piece of Titian's drapery, produce their essential effects. If you do not feel it, no one can by reasoning make you feel it.

John Ruskin

I would call the attention of the reader to the difference between "reason" and "reasoning." Reason is a light, reasoning a process. Reason is a faculty, reasoning an exercise of that faculty. Reasoning proceeds from one truth to another by means of argumentation. This generally involves the whole mind in labor and complexity. But reason does not exist merely in order to engage in reasoning. The process is a means to an end. The true fulfillment of reason as a faculty is found when it can embrace the truth simply and without labor in the light of single intuition.

Thomas Merton

Science has great skills, great reasoning and great intelligence in combining effects. It knows HOW to do many things but it admittedly does not know the WHY of anything.

Walter Russell

In 2001, a systematic review of five studies revealed that roughly half of all chiropractic patients experience temporary adverse effects, such as pain, numbness, stiffness, dizziness and headaches. These are relatively minor effects, but the frequency is very high, and this has to be weighed against the limited benefit offered by chiropractors.
