Before I got married I had six theories about bringing up children; now I have six children and no theories.

As quoted in The New Speaker's Treasury of Wit and Wisdom (1958) by Herbert Victor ProchnowJohn Wilmot
Our view of life must account for how we know life; biological theories must allow for their own discovery and employment. Theories of evolution must provide for the creative acts which brought such theories into existence. Beginning with our own embodiment our theory of knowledge must endorse the ways we manifestly transcend our embodiment by acts of indwelling and extension into more subtle and intangible realms of being, where we meet our ultimate ends.
Michael Polanyi
Theory is a dirty word in some managerial quarters. That is rather curious, because all of us, managers especially, can no more get along without theories than libraries can get along without catalogs — and for the same reason: theories help us make sense of incoming information.
Henry Mintzberg
[M]ost of Marx' theories which are not mistaken are meaningless. Marx remained influential, however: his influence never was based on the scientific truth-content of his theories but on their psychological appeal.
Karl Marx
One reason you tend to doubt conspiracy theories when you've worked in government is because you know government is not nearly competent enough to carry off elaborate theories. It's a banal explanation, but imagine how efficient it would need to be.
Philip D. Zelikow
There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists. ... Many of these theories have been killed off only when some decisive experiment exposed their incorrectness. .. Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.
