The importance of historical truths.

It ought farther to be observed respecting truths in general, that those are always most valuable which are most historical; that is, which tell us most about the past and future states of the object to which they belong. In a tree, for instance, it is more important to give the appearance of energy and elasticity in the limbs which is indicative of growth and life, than any particular character of leaf, or texture of bough. It is more important that we should feel that the uppermost sprays are creeping higher and higher into the sky, and be impressed with the current of life and motion which is animating every fibre, than that we should know the exact pitch of relief with which those fibres are thrown out against the sky. For the first truths tell us tales about the tree, about what it has been, and will be, while the last are characteristic of it only in its present state, and are in no way talkative about themselves. Talkative facts are always more interesting and more important than silent ones.
