“There is a science of Dynamics in man's fortunes and nature, as well as of Mechanics. There is a science which treats of, and practically addresses, the primary, unmodified forces and energies of man, the mysterious springs of Love, and Fear, and Wonder, of Enthusiasm, Poetry, Religion, all which have a truly vital and infinite character; as well as a science which practically addresses the finite, modified developments of these, when they take the shape of immediate “motives,” as hope of reward, or as fear of punishment.
Now it is certain, that in former times the wise men, the enlightened lovers of their kind, who appeared generally as Moralists, Poets or Priests, did, without neglecting the Mechanical province, deal chiefly with the Dynamical; applying themselves chiefly to regulate, increase and purify the inward primary powers of man; and fancying that herein lay the main difficulty, and the best service they could undertake. But a wide difference is manifest in our age. For the wise men, who now appear as Political Philosophers, deal exclusively with the Mechanical province; and occupying themselves in counting-up and estimating men's motives, strive by curious checking and balancing, and other adjustments of Profit and Loss, to guide them to their true advantage”
