The most generous views will, in such cases, frequently lead to the most nefarious actions. A Cranmer will be incited to the burning of heretics, and a Digby contrive the Gunpowder Treason. But, to leave these extreme instances: in all cases where mistaken virtue leads to cruel and tyrannical actions, the mind will be rendered discontented and morose by the actions it perpetrates. Truth, immortal and ever present truth, is so powerful, that, in spite of all his prejudices, the upright man will suspect himself when he resolves upon an action that is at war with the plainest principles of morality. He will become melancholy, dissatisfied and anxious. His firmness will degenerate into obstinacy, and his justice into in exorable severity.
The further he pursues his system, the more erroneous will he become. The further he pursues it, the less will he be satisfied with it. As truth is an endless source of tranquillity and delight, error will be a prolific fountain of new mistakes and discontent.
As to the third point, which is most essential to the enquiry in which we are engaged, the tendency of truth to the improvement of our political institutions, there can be little room for scepticism or controversy. If politics be a science, investigation must be the means of unfolding it.
If men resemble each other in more numerous and essential particulars than those in which they differ, if the best purposes that can be accomplished respecting them be to make them free, virtuous and wise, there must be one best method of advancing these common purposes, one best mode of social existence deducible from the principles of their nature. If truth be one, there must be one code of truths on the subject of our reciprocal duties.
Nor is investigation only the best mode of ascertaining the principles of political justice and happiness; it is also the best mode of introducing and establishing them. Discussion is the path that leads to discovery and demonstration. Motives ferment in the minds of great bodies of men, till their modes of society experience a variation, not less memorable than the variation of their sentiments. The more familiar the mind becomes with the ideas of which these motives consist, and the propositions that express them, the more irresistibly is it propelled to a general system of proceeding in correspondence with them.
A proposition which, however evident in itself, seems never to have been considered with the attention it deserves is that which affirms the connection between understanding and virtue. Can an honest ploughman be as virtuous as Cato? Is a man of weak intellects and narrow education as capable of moral excellence as the sublimest genius or the mind most stored with information and science?
To determine these questions it is necessary we should recollect the nature of virtue. Considered as a personal quality, it consists in the disposition of the mind, and may be defined a desire to promote the happiness of intelligent beings in general, the quantity of virtue being as the quantity of desire. Now desire is wholly inseparable from preference, or a perception of the excellence, real or supposed, of any object. I say real or supposed, for aIl object totally destitute of real and intrinsic excellence may become an object of desire on account of the imaginary excellence that is ascribed to it. Nor is this the only mistake to which human intellect is liable.
We may desire an object of absolute excellence, not for its real and genuine recommendations, but for some fictitious attractions we may impute to it.
This is always in some degree the case when a beneficial action is performed from an ill motive.
How far is this mistake compatible with real virtue? If I desire the happiness of intelligent beings, without a strong and vivid perception of what it is in which their happiness consists, can this desire be admitted for virtuous? Nothing seems more inconsistent with our ideas of virtue.
A virtuous preference is the preference of an object for the sake of certain qualities which really be long to it. To attribute virtue to any other species of preference would be nearly the same as to suppose that an accidental effect of my conduct, which was out of my view at the time of adopting it, might entitle me to the appellation of virtuous.
Hence it appears, first, that virtue consists in a desire of the happiness of the species: and, secondly, that that desire only can be eminently virtuous which flows from a distinct perception of the value, and consequently of the nature, of the thing desired. But how extensive must be the capacity that comprehends the full value and the real ingredients of true happiness?
It must begin with a collective idea of the human species. It must discriminate, among the different causes that produce a pleasurable state of mind, that which produces the most exquisite and durable pleasure. Eminent virtue requires that I should have a grand view of the tendency of knowledge to produce happiness, and of just political institution to favour the progress of knowledge. It demands that I should perceive in what manner social intercourse may be made conducive to virtue and felicity, and imagine the unspeakable advantages that may arise from a coincidence and succession of generous efforts. These things are necessary, not merely for the purpose of enabling me to employ my virtuous disposition in the best manner, but also of giving to that disposition a just animation and vigour. God, according to the ideas usually conceived of that being, is more benevolent than man because he has a constant and clear perception of the nature of that end which his providence pursues.
A further proof that a powerful understanding is in separable from eminent virtue will suggest itself, if we recollect that earnest desire, in matters that fall within the compass of human exertion, never fails in some degree to generate capacity.
