But, though the language of the necessarian is at war with the indestructible feelings of the human mind, and though his demonstrations will for ever crumble into dust, when brought to the test of the activity of real life, yet his doctrines, to the reflecting and enlightened, will by no means be without their use. In the sobriety of the closet, we inevitably assent to his conclusions; nor is it easy to conceive how a rational man and a philosopher abstractedly can entertain a doubt of the necessity of human actions. And the number of these persons is perpetually increasing; enlarged and dispassionate views of the nature of man and the laws of the universe are rapidly spreading in the world. We cannot indeed divest ourselves of love and hatred, of the sentiments of praise and blame, and the ideas of virtue, duty, obligation, debt, bond, right, claim, sin, crime, guilt, merit and desert. And, if we could do so, the effects would be most pernicious, and the world be rendered a blank. We shall however unquestionably, as our minds grow enlarged, be brought to the entire and unreserved conviction, that man is a machine, that he is governed by external impulses, and is to be regarded as the medium only through the intervention of which previously existing causes are enabled to produce certain effects. We shall see, according to an expressive phrase, that he "could not help it," and, of consequence, while we look down from the high tower of philosophy upon the scene of human affairs, our prevailing emotion will be pity, even towards the criminal, who, from the qualities he brought into the world, and the various circumstances which act upon him from infancy, and form his character, is impelled to be the means of the evils, which we view with so profound disapprobation, and the existence of which we so entirely regret. There is an old axiom of philosophy, which counsels us to "think with the learned, and talk with the vulgar;" and the practical application of this axiom runs through the whole scene of human affairs. Thus the most learned astronomer talks of the rising and setting of the sun, and forgets in his ordinary discourse that the earth is not for ever at rest, and does not constitute the centre of the universe. Thus, however we reason respecting the attributes of inanimate matter and the nature of sensation, it never occurs to us, when occupied with the affairs of actual life, that there is no heat in fire, and no colour in the rainbow.
