Deduction Quotes

It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.

Arthur Conan Doyle

There's also a possibility that the landlord is in there right now, wearing women's undergarments. Or a drug addict is inside stealing jewelry.Or a boatload of recent Chinese immigrants without a television watching Russia play Finland in hockey and placing bets over beer. You have no idea what's behind that door. You can't just pick the options within your field of vision. Reality comes from everywhere. At best, you can narrow down the likelihoods. But in the end, it's not a matter of deduction. It's a matter of fact. One bullet will kill you if you're stupid or unlucky. So at least don't be stupid

Logical reasoning may be a most convenient means of mental communication for covering short distances, but the curvature of the earth, alas, is reflected even in logic: an ideally rational progression of thought will finally bring you back to the point of departure where you return aware of the simplicity of genius, with a delightful sensation that you have embraced truth, while actually you have merely embraced your own self... anything you might term a deduction already exposes the flaw: logical development inexorably becomes an envelopment.

Vladimir Nabokov

All people, whether Aspie or neuro-typical are predisposed by their society to make guesses, jump to conclusions and then seek to defend those conclusions, regardless of logic or changing circumstance.

What a lovely thing a rose is!"He walked past the couch to the open window and held up the drooping stalk of a moss-rose, looking down at the dainty blend of crimson and green. It was a new phase of his character to me, for I had never before seen him show any keen interest in natural objects. "There is nothing in which deduction is so necessary as religion," said he, leaning with his back against the shutters. "It can be built up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. All other things, our powers, our desires, our food, are all really necessary for our existence in the first instance. But this rose is an extra. Its smell and its color are an embellishment of life, not a condition of it. It is only goodness which gives extras, and so I say again that we have much to hope from the flowers.
