LETTER XXV.

My Lord,

I have no great opinion of Ethics treated as a science, according to the form of the old schoolmen. Great ingenuity is indeed shown in them; but it is ingenuity which tends to confound the plain and natural distinction of good and evil, written on the heart of man in the luminous characters of a sunbeam. In the hands of the casuists, ethics become a science, not very favourable to that simplicity of mind which contributes more to honesty and to true enjoyment, than all the precepts of the most celebrated moralists. Feel as you ought to feel, and, with the direction of common sense, you will, for the most part, act as you ought to act.

Since, however, the art of man has reduced ethics to the form of a system and a science, it will be proper for you to give it some of your attention. To know something of them systematically, is a necessary part of a comprehensive education. I must mention by the way, that the glorious gospel rule, of doing to others as we wish they should do unto us, constitutes an epitome of many folios, in casuistical and systematical morality.

There is a pretty compendium of moral philosophy by Francis Hutcheson, whose little book on metaphysics I have already mentioned to you. You will find in it the elements of ethics, natural jurisprudence, economics, and politics, clearly and succinctly displayed. This will be a very useful introduction, as the author justly professes it to be, to the ancient moralists, to Plato, Aristotle, Xenophon, and Cicero; and to the moderns, Grotius, Cumberland, Puffendorf, and Harrington.

These great authors you will read as your leisure and inclination may lead you. The celebrity of Puffendorf's book de Officio Hominis et Civis is such, that I think you will not rest satisfied, without giving it a very attentive perusal, after reading Hutcheson. If you should make yourself a perfect master of Hutcheson's Compendious Institution, and of Puffendorf, you will not be at a loss on the subject of sytematic or scientific ethics, and your understanding will be much enlightened by the study.

Paley's Book on Moral and Political Philosophy has singular merit; for it is entertaining as well as highly instructive; a circumstance rather uncommon in scientific treatises on morals. Remember, however, that I do not entirely subscribe to all his doctrines, several of which appear to be a little too casuistical; I will not say, jesuitical, for I greatly respect the author. Read it with attention; and make your own reflections on some parts, which appear to be accommodated to things as they are, rather than as they should be. The Archdeacon acknowledges himself greatly indebted to Search's Light of Nature; the three or four last volumes of which, certainly abound in excellent thoughts, and original illustrations; I mean those volumes, which have in the title-page, “The Light of Nature and the Gospel blended.” This work is voluminous, verbose, and heavy; and, notwithstanding its great merit, difficult to be read without weariness and occasional disgust, arising from prolixity. Yet it abounds with new ideas and valuable doctrine.

If you can find time, and feel an inclination for these studies, I must not omit to urge your reading Grotius on the Rights of War and Peace. It is certainly a master-piece of its kind; and therefore should be known by every general scholar. At the same time, I cannot but be a little apprehensive lest your style as an orator should suffer by a long study of compositions, rather jejune and destitute of grace. They are merely skeletons; whereas I wish you to study complete models, where the features glow with life, and the limbs are nerved with vigour. I do not introduce you to the hortus siccus, when you can see the lily and rose blooming and flourishing with life and beauty, in your garden.

To learn ethics, I should therefore rather choose to refer you to such writers as Plato, Cicero, and Addison. There you will behold the body of truth, adorned with beauty and the complexion of health. In Puffendorf, Grotius, and other systematic writers, you see truth, indeed, but you see her lovely form disfigured by the knife of the anatomist.

After having read a volume or two of the best writers in the systematic way, in order to obtain an idea of ethics, thus treated as a science, you will proceed to imbibe morality, as the bee sucks honey, from every book of history, poetry, oratory, and divinity, which falls under your notice. You will roam from flower to flower, and return loaded to your hive.

The book of nature, and the book of the world, lie open to you; books little read by the Grotius's and the Barbeyracs. There, with the assistance of the knowledge you have already acquired, and will hereafter increase, in your study, you will comment on men and manners; always measuring the morality of actions by the golden canon already repeated, of doing to others as you wish they should do unto you.

I am, &c.
