“[Physicists and philosophers] stick stubbornly to the principles of a mechanistic interpretation of the world after physics has, in its factual structure, already outgrown the latter. They have the same excuse as the inhabitant of the mainland who for the first time travels on the open sea: he will desperately try to stay in sight of the vanishing coast line, as long as there is no other coast in sight, towards which he steers.”

Jonathan Edwards, A Treatise Concerning Religious Affections (1746), PART II : Showing What Are No Certain Signs That Religious Affections Are Truly Gracious, Or That They Are Not, Ch. 11: Nothing can be certainly known of the nature of Religious Affections, that they much dispose persons with their mouths to praise and glorify God. <!-- (1831 edition), p. 194, also in Complete Christian Classics (1999), Vol. 1, p. 365 -->
Context: !-- He who has a false hope, has not that sight of his own corruptions which the saint has. A true Christian has ten times more to do with his heart and its corruptions, than a hypocrite: and the sins of his heart and practice, appear to him in their blackness; they look dreadful; and it often appears a very mysterious thing, that any grace can be consistent with such corruption, or should be in such a heart. But a false hope hides corruption, covers it all over, and the hypocrite looks clean and bright in his own eyes.
--> There are two sorts of hypocrites: one that are deceived with their outward morality and external religion; many of which are professed Arminians, in the doctrine of justification: and the other, are those that are deceived with false discoveries and elevations; which often cry down works, and men's own righteousness, and talk much of free grace; but at the same time make a righteousness of their discoveries, and of their humiliation, and exalt themselves to heaven with them. These two kinds of hypocrites, Mr. Shepard, in his Exposition of the Parable of the Ten Virgins, distinguishes by the names of legal and evangelical hypocrites; and often speaks of the latter as the worst. And it is evident that the latter are commonly by far the most confident in their hope, and with the most difficulty brought off from it: I have scarcely known the instance of such a one, in my life, that has been undeceived.

On the Uses and Transformations of Linear Algebra (1875)
Context: Some definite interpretation of a linear algebra would, at first sight, appear indispensable to its successful application. But on the contrary, it is a singular fact, and one quite consonant with the principles of sound logic, that its first and general use is mostly to be expected from its want of significance. The interpretation is a trammel to the use. Symbols are essential to comprehensive argument.
