But, though optimism, pursued into its consequences, is destructive of the distinction between virtue and vice, or rather teaches that there neither is nor can be such a thing as vice, yet it is the fate of this, like many other errors, that the truths which lie undeveloped in the mind, and cannot be deracinated, serve to check its influence and counteract its evil tendency.
It may however be suspected that, while its pernicious effects are thus counteracted, they are not destroyed. It is unavoidable that men should, in some respects, imitate what they persuade themselves is right. Thus in religion, those persons who believe that a large portion of mankind are objects of God's wrath, and reserved for eternal perdition, can never be prevailed on to regard, with a true and genuine sympathy, those whom God has cursed. In the same manner it will probably happen in the present case: those who believe that all the unfortunate events and sufferings that exist in the world will be found, in some mysterious way, to have been the fittest instruments of universal good, are in danger of being less scrupulous than they ought to be, in the means they shall themselves select for the accomplishment of their purposes. If pain, horrors and devastation be frequently found means of kindness in the system of the universe, it is impossible to assign a good reason why they should not be such under the direction of man.
There is another crude notion diffused in the world, which the principle of optimism is calculated to encourage, and which the views here explained have a tendency to correct. It is not uncommon to congratulate ourselves upon the perverseness and misconduct of those whose views we oppose, under the imagination that such misconduct conduces to the more speedy subversion of error and establishment of justice. But the maxim is safer and better founded than this, which should instruct us that we "rejoice not in evil, but rejoice in the truth." It has already appeared that it is a matter of great delicacy and difficulty, to decide in favour of pain and calamity, as the probable means of a preponderance of good. It was sufficiently seen, when we treated of resistance and revolutions, that the angry passions are not the most promising instruments of human happiness. A perverse conduct tends to the production of confusion and violence. A government that employed every species of persecution against those who should desire its reform, and that involved the country over which it presided in war, for the purpose of checking or exterminating sentiments of reason and equality, would do harm, and not good. It might indeed defeat its own purposes; but it would produce resentment and contention. It might excite a revulsion in the public mind against its designs; but this revulsion would be the offspring of irritation, and not of the understanding. Diminish the irritation, and the progress of real knowledge would be more substantial and salutary.
Real knowledge is benevolent, not cruel and retaliating. The change that grows up among any people from a calm conviction of the absurdity of their former errors, is of the most admirable sort; but the change that grows from distress, distemper and crisis, is an explosion pregnant with fate to thousands. From all these considerations it appears, that every departure from enormous vice, should be accounted as so much gained to the cause of general happiness.
Let any person who entertains the contrary opinion ask himself whether, if he had a part in the government we have supposed, he would think himself obliged to act, in the manner in which he professes to desire the government should act? If, as he imagines, that action be most conducive to the public good, most undoubtedly, were it his own case, he ought to adopt it. Again, would he advise or incite the government, in any way, to this perverse conduct? There cannot be a clearer principle in morals, than "that the action it would be vice in us to adopt, it is vice in us to desire to see adopted by another."
A further consequence that flows from these speculations, is relative to the persecution and sufferings to be endured by the advocates of justice.
The same reasoning that has persuaded men to rejoice in beholding acts of oppression has led them to court oppression and martyrdom. A sound philosophy, it should seem, would never instigate us to provoke the passions of others, or to regard injustice as the suitable means of public happiness. It is reason, and not anger, that will benefit mankind. Dispassionate enquiry, not bitterness and resentment, is the parent of reform. The wise man will avoid persecution, because a protracted life, and an unfettered liberty, are likely to enable him to produce a greater sum of good. He will avoid persecution, because he will be unwilling to add fuel to the flames of contention. He will regret it when it arrives, because he believes it to be both wicked and mischievous. But he will not avoid it by the sacrifice of a virtuous, but tempered, activity. He will not regret it with a mean and pusillanimous spirit, but will meet it, when it can no longer be prevented, with that dignity of soul and tranquillity of temper that are characteristic of true wisdom. He will not imagine that the cause of truth will perish, though he should be destroyed. He will make the best of the situation to which he is reduced, and endeavour that his death, like his life, may be of use to mankind.
