The moral equality is still less open to reasonable exception. By moral equality I understand, the propriety of applying one unalterable rule of justice to every case that may arise. This cannot be questioned, but upon arguments that would subvert the very nature of virtue. "Equality," it has been affirmed, "will always be an unintelligible fiction, so long as the capacities of men shall be unequal, and their pretended claims have neither guarantee nor sanction by which they can be enforced." But surely justice is sufficiently intelligible in its own nature, abstractedly from the consideration whether it be or be not reduced into practice. Justice has relation to beings endowed with perception, and capable of pleasure and pain. Now it immediately results from the nature of such beings, independently of any arbitrary constitution, that pleasure is agreeable and pain odious, pleasure to be desired and pain to be disapproved. It is therefore just and reasonable that such beings should contribute, so far as it lies in their power, to the pleasure and benefit of each other. Among pleasures, some are more exquisite, more unalloyed and less precarious than others.
It is just that these should be preferred.
From these simple principles we may deduce the moral equality of mankind.
We are partakers of a common nature, and the same causes that contribute to the benefit of one will contribute to the benefit of another. Our senses and faculties are of the same denomination. Our pleasures and pains will therefore be alike. We are all of us endowed with reason, able to compare, to judge and to infer. The improvement therefore which is to be desired for one is to be desired for another. We shall be provident for ourselves, and useful to each other in proportion as we rise above the sphere of prejudice.
The same independence, the same freedom from any such restraint, as should prevent us from giving the reins to our own understanding, or from uttering, upon all occasions, whatever we think to be true, will conduce to the improvement of all. There are certain opportunities and a certain situation most advantageous to every human being, and it is just that these should be communicated to all, as nearly as the general economy will permit.
There is indeed one species of moral inequality, parallel to the physical inequality that has been already described. The treatment to which men are entitled is to be measured by their merits and their virtues. That country would not be the seat of wisdom and reason where the benefactor of his species was regarded with no greater degree of complacence than their enemy. But in reality this distinction, so far from being adverse to equality in any tenable sense, is friendly to it, and is accordingly known by the appellation of equity, a term derived from the same origin.
Though in some sense all exception, it tends to the same purpose to which the principle itself is indebted for its value. It is calculated lo infuse into every bosom an emulation of excellence. The thing really lo be desired is the removing as much as possible arbitrary distinctions, and leaving to talents and virtue the field of exertion unimpaired. We should endeavour to afford to all the same opportunities and the same encouragement, and to render justice the common interest and choice.
It should be observed that the object of this chapter is barely to present a general outline of the principle of equality. The practical inferences that flow from it must remain to be detailed under subsequent heads of enquiry.
