“A problem is determinate if it has a definite number of solutions, indeterminate if it has an indefinite number of solutions, and impossible if it has no solution.” – G. A. Wentworth, Plane Geometry (emphases in original)
“Failure, then, failure! so the world stamps us at every turn. We strew it with our blunders, our misdeeds, our lost opportunities, with all the memorials of our inadequacy to our vocation. And with what a damning emphasis does it then blot us out! No easy fine, no mere apology or formal expiation, will satisfy the world’s demands, but every pound of flesh exacted is soaked with all its blood. The subtlest forms of suffering known to man are connected with the poisonous humiliations incidental to these results. And they are pivotal human experiences. A process so ubiquitous and everlasting is evidently an integral part of life. ‘There is indeed one element in human destiny,’ Robert Louis Stevenson writes, ‘that not blindness itself can controvert. Whatever else we are intended to do, we are not intended to succeed; failure is the fate allotted.’” – William James, The Varieties of Religious Experience
