Certainty Quotes - page 2
When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. It is much more nearly certain that we are assembled here tonight than it is that this or that political party is in the right. Certainly there are degrees of certainty, and one should be very careful to emphasize that fact, because otherwise one is landed in an utter skepticism, and complete skepticism would, of course, be totally barren and completely useless.
Bertrand Russell
As the future is never known with certainty, the evaluation of the prospective benefits requires the formation of expectations. An acceptable house, partner or job, then, is one that offers an expected stream of future benefit that has a value in excess of the option to continue to search for an even better alternative.
Dale T. Mortensen
The new education must consist essentially in this, that it completely destroys freedom of will in the soil which it undertakes to cultivate, and produces on the contrary strict necessity in the decisions of the will, the opposite being impossible. Such a will can henceforth be relied on with confidence and certainty.
Johann Gottlieb Fichte
A science only advances with certainty, when the plan of inquiry and the object of our researches have been clearly defined; otherwise a small number of truths are loosely laid hold of, without their connexion being perceived, and numerous errors, without being enabled to detect their fallacy.
Jean-Baptiste Say
Organisms [...] are directed and limited by their past. They must remain imperfect in their form and function, and to that extent unpredictable since they are not optimal machines. We cannot know their future with certainty, if only because a myriad of quirky functional shifts lie within the capacity of any feature, however well adapted to a present role.
Stephen Jay Gould
All I can tell you with certainty is that I, for one, have no self, and that I am unwilling or unable to perpetrate upon myself the joke of a self.... What I have instead is a variety of impersonations I can do, and not only of myself - a troupe of players that I have internalised, a permanent company of actors that I can call upon when a self is required.... I am a theater and nothing more than a theater.
Philip Roth
