It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.
The truth, the whole truth, nothing but the truth. Little men are dissolved in it. If there is any gold, truth makes it shine more brightly. . . .Truth, even in the mouth of an informer, a spy, a briber, can become bigger than anybody who tries to destroy it. Truth survives.
There are and can be only two ways of searching into and discovering truth. The one flies from the senses and particulars to the most general axioms, and from these principles, the truth of which it takes for settled and immovable, proceeds to judgment and to the discovery of middle axioms. And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.
