Logic is an organized way of going wrong with confidence.
Charles F. Kettering (1876-1958) American inventor, engineer, researcher, businessman
“Kettering’s Law,” from address before American Society of Mechanical Engineers (c. 1944)
Quoted in Heinlein, The Number of the Beast (1980). Alternately quoted:
- "Beware logic. Logic is an organized way to go wrong -- with confidence."
- Logic is an organized way to go wrong with confidence. We should all know by now that a logical course is not always the right one."
Sometimes referred to "Kettering's Observation."
Cited in Food Industries magazine, vol. 16 (1944), referring to the speech being "recent" (the magazine is also referred to as Food Engineering).
This site previously incorrectly attributed the quote to Iris Murdoch. That attribution seems to have been duplicated at some other sites, but was an error. I have also found citations to L. Walter Lundell and Karl Popper.
Another "Kettering's Law" that is referenced is: "Parts left out cost nothing, require no maintenance, and do not fail."
In all affairs — love, religion, politics or business — it’s a healthy idea, now and then, to hang a question mark on the things you have long taken for granted.
Bertrand Russell (1872-1970) English mathematician and philosopher
(Attributed)
Widely attributed to Russell, but not found in any of his online published works or cited to any source.
There are numerous variations on this quote, e.g.,
In all affairs it's a healthy idea now and then to hang a question mark on the things you have taken for granted.
And mixes and matches between those two.
Earliest references of long-form quotation I could find:I also found in Alexander Chittick, Social Evolution, "The Evolution of Capital and Labor" (1919), regarding the plight of laborers:
- Readers Digest, "Quotable Quotes" filler (1940-08)
- Forbes, "Thoughts on the Business of Life" (1950-02-01)
They should be taught [...] to take nothing for granted in love, religion, politics, or business.
The combination of taking for granted and the same list of four affair topics seems more than coincidence. Was Chittick riffing off of an unfound Russell comment? Did someone attribute a variation of Chittick's passage to Russell? The answer is unclear.
How many a debate could have been deflated into a single paragraph if the disputants had dared to define their terms?
William James (Will) Durant (1885-1981) American historian, teacher, philosopher
The Story of Philosophy, ch. 2 “Aristotle and Greek Science,” sec. 3 “The Foundation of Logic” (1926)
(Source)
This quotation is frequently misattributed (without citation) to Aristotle (sometimes using "dispute" instead of "debate"), but none of the sources pre-date this passage by Durant. Durant is speaking of Aristotle's development of logic, and his focus on definitions, but the full passage in context is clearly not a quotation:
There was a hint of this new science in Socrates’ maddening insistence on definitions, and in Plato’s constant refining of every concept. Aristotle’s little treatise on Definitions shows how his logic found nourishment at this source. “If you wish to converse with me,” said Voltaire, “define your terms.” How many a debate would have been deflated into a paragraph if the disputants had dared to define their terms! This is the alpha and omega of logic, the heart and soul of it, that every important term in serious discourse shall be subjected to strictest scrutiny and definition. It is difficult, and ruthlessly tests the mind; but once done it is half of any task.
