The bullet which he aims direct proceeds by a curve, and when you wish to strike a certain point in space, you impel your bombshell along its cruel parabola.

None of your men of science have drawn from this fact the simple deduction that the Curve is the law of the material worlds and the Straight line that of the Spiritual worlds; one is the theory of finite creations, the other the theory of the infinite.

Man, who alone in the world has a knowledge of the Infinite, can alone know the straight line; he alone has the sense of verticality placed in a special organ.

A fondness for the creations of the curve would seem to be in certain men an indication of the impurity of their nature still conjoined to the material substances which engender us; and the love of great souls for the straight line seems to show in them an intuition of heaven.

Between these two lines there is a gulf fixed like that between the finite and the infinite, between matter and spirit, between man and the idea, between motion and the object moved, between the creature and God.
