This most important truth may be stated in a somewhat different form. Whenever a man is eminently deficient in any virtue, it, of course, follows that his character is imperfect, but it does not necessarily follow that he is not in other respects moral and virtuous. There is, however, usually some one virtue, which I may term rudimentary, which is brought forward so prominently before the world, as the first condition of moral excellence, that it may be safely inferred that a man who has absolutely neglected it is entirely indifferent to moral culture. Rudimentary virtues vary in different ages, nations, and classes. Thus, in the great republics of antiquity patriotism was rudimentary, for it was so assiduously cultivated, that it appeared at once the most obvious and the most essential of duties. Among ourselves much private virtue may co-exist with complete indifference to national interests. In the monastic period, and in a somewhat different form in the age of chivalry, a spirit of reverential obedience was rudimentary, and the basis of all moral progress; but we may now frequently find a good man without it, his moral energies having been cultivated in other directions. Common truthfulness and honesty, as I have already said, are rudimentary virtues in industrial societies, but not in others. Chastity, in England at least, is a rudimentary female virtue, but scarcely a rudimentary virtue among men, and it has not been in all ages, and is not now in all countries, rudimentary among women. There is no more important task devolving upon a moral historian, than to discover in each period the rudimentary virtue, for it regulates in a great degree the position assigned to all others.
From the considerations I have urged, it will appear that there is considerable danger in proposing too absolutely a single character, however admirable, as the model to which all men must necessarily conform. A character may be perfect in its own kind, but no character can possibly embrace all types of perfection; for, as we have seen, the perfection of a type depends not only upon the virtues that constitute it, but also upon the order and prominence assigned to them. All that can be expected in an ideal is, that it should be perfect of its own kind, and should exhibit the type most needed in its age, and most widely useful to mankind. The Christian type is the glorification of the amiable, as the Stoic type was that of the heroic qualities, and this is one of the reasons why Christianity is so much more fitted than Stoicism to preside over civilisation, for the more society is organised and civilised, the greater is the scope for the amiable, and the less for the heroic qualities.
The history of that moral intolerance which endeavours to reduce all characters to a single type has never, I think, been examined as it deserves, and I shall frequently have occasion to advert to it in the following pages. No one can have failed to observe how common it is for men to make their own tastes or excellences the measure of all goodness, pronouncing all that is broadly different from them to be imperfect or low, or of a secondary value. And this, which is usually attributed to vanity, is probably in most cases much more due to feebleness of imagination, to the difficulty most men have in conceiving in their minds an order of character fundamentally different from their own. A good man can usually sympathise much more with a very imperfect character of his own type than with a far more perfect one of a different type. To this cause, quite as much as to historical causes or occasional divergences of interest, may be traced the extreme difficulty of effecting cordial international friendships, especially in those cases when a difference of race coincides with the difference of nationality. Each nation has a distinct type of excellence, each esteems the virtues in which it excels, and in which its neighbours are often most deficient, incomparably the greatest. Each regards with especial antipathy the vices from which it is most free, and to which its neighbours maybe most addicted. Hence arises a mingled feeling of contempt and dislike, from which the more enlightened minds are, indeed, soon emancipated, but which constitutes the popular sentiment.
The type of character of every individual depends partly upon innate temperament and partly upon external circumstances. A warlike, a refined, an industrial society each evokes and requires its specific qualities, and produces its appropriate type. If a man of a different type arise—if, for example, a man formed by nature to exhibit to the highest perfection the virtues of gentleness or meekness, be born in the midst of a fierce military society—he will find no suitable scope for action, he will jar with his age, and his type will be regarded with disfavour. And the effect of this opposition is not simply that he will not be appreciated as he deserves, he will also never succeed in developing his own distinctive virtues as they would have been developed under other circumstances. Everything will be against him—the force of education, the habits of society, the opinions of mankind, even his own sense of duty. All the highest models of excellence about him being formed on a different type, his very efforts to improve his being will dull the qualities in which nature intended him to excel. If, on the other hand, a man with naturally heroic qualities be born in a society which pre-eminently values heroism, he will not only be more appreciated, he will also, under the concurrence of favourable circumstances, carry his heroism to a far higher point than would otherwise have been possible. Hence changing circumstances produce changing types, and hence, too, the possibility of moral history and the necessity of uniting it with general history. Religions, considered as moral teachers, are realised and effective only when their moral teaching is in conformity with the tendency of their age. If any part of it is not so, that part will be either openly abandoned, or refined away, or tacitly neglected. Among the ancients, the co-existence of the Epicurean and Stoical schools, which offered to the world two entirely different archetypes of virtue, secured in a very remarkable manner the recognition of different kinds of excellence; for although each of these schools often attained a pre-eminence, neither ever succeeded in wholly destroying or discrediting the other.
Of the two elements that compose the moral condition of mankind, our generalised knowledge is almost restricted to one. We know much of the ways in which political, social, or intellectual causes act upon character, but scarcely anything of the laws that govern innate disposition, of the reasons and extent of the natural moral diversities of individuals or races. I think, however, that most persons who reflect upon the subject will conclude that the progress of medicine, revealing the physical causes of different moral predispositions, is likely to place a very large measure of knowledge on this point within our reach. Of all the great branches of human knowledge, medicine is that in which the accomplished results are most obviously imperfect and provisional, in which the field of unrealised possibilities is most extensive, and from which, if the human mind were directed to it, as it has been during the past century to locomotive and other industrial inventions, the most splendid results might be expected. Our almost absolute ignorance of the causes of some of the most fatal diseases, and the empirical nature of nearly all our best medical treatment, have been often recognised. The medicine of inhalation is still in its infancy, and yet it is by inhalation that Nature produces most of her diseases, and effects most of her cures. The medical power of electricity, which of all known agencies bears most resemblance to life, is almost unexplored. The discovery of anæsthetics has in our own day opened out a field of inestimable importance, and the proved possibility, under certain physical conditions, of governing by external suggestions the whole current of the feelings and emotions, may possibly contribute yet further to the alleviation of suffering, and perhaps to that euthanasia which Bacon proposed
