"But were these more dubious, and were it no more than a splendid error; yet considering that it works so often in the right direction, it were enough to urge in its behalf, that it is a principle of real _action_, and approved energy. That, as much as practice is better than theory, and solid realties than empty speculation, so much is it to be preferred for general use before those higher principles of morals, which however just and excellent in themselves, you would in vain attempt to bring home to the 'business and bosoms of mankind' at large. Reject not then a principle thus universal in its influence, thus valuable in its effects; a principle, which, by whatever name you may please to call it, acts by motives and considerations suited to our condition; and which, putting it at the very lowest, must be confessed, in our present infirm state, to be an habitual aid and an ever present support to the feebleness of virtue! In a selfish world it produces the effects of disinterestedness, and when public spirit is extinct, it supplies the want of patriotism. Let us therefore with gratitude avail ourselves of its help, and not relinquish the good which it freely offers, from we know not what vain dreams of impracticable purity and unattainable perfection." All this and much more might be urged by the advocates of this favourite principle. It would be however no difficult task to shew that it by no means merits this high eulogium. To say nothing of that larger part of the argument of our opponents, which betrays, and even proceeds upon, that mischievous notion of the innocence of error, against which we have already entered our formal protest, the principle in question is manifestly of a most inconstant and variable nature; as inconstant and variable as the innumerably diversified modes of fashions, habits, and opinions in different periods and societies. What it tolerates in one age, it forbids in another; what in one country it prescribes and applauds, in another it condemns and stigmatizes! Obviously and openly, it often takes vice into its patronage, and sets itself in direct opposition to virtue. It is calculated to produce rather the _appearance_ than the _reality_ of excellence; and at best not to check the _love_ but only the _commission_ of vice. Much of this indeed was seen and acknowledged by the philosophers, and even by the poets, of the Pagan world. They declaimed against it as a mutable and inconsistent principle; they lamented the fatal effects which, under the name of false glory, it had produced on the peace and happiness of mankind. They condemned the pursuit of it when it led its followers out of the path of virtue, and taught that the praise of the wise and of the good only was to be desired.
