BACHYE’S “Guide to the Duties of the Heart” is the unique work that first linked the ethical science of the West with the emotional and spiritual morality of the East. It combines, in an artistic unity, elements drawn from the philosophy and contemplative mysticism of the Arabs, from Biblical and Rabbinic Judaism, and from Greek thought. By exhibiting the spiritual foundations of universal Ethics, and of the moral law of the Bible, in the light of pure reason, Bachye prepared the way for finding that common ground on which, wholly or in part, all the moral religions, and all the non religious systems of morality, are rooted. Therefore, although actually written in Spain, a land of the West, it forms a fitting opening volume for the “Wisdom of the East Series.” Only a small part of the original finds a place in the following pages; but I have in my translation—sometimes literal, now and again a summarised —endeavoured to give a selection of passages connected by the author’s central thought, and showing his line of argument and the aim and spirit of his work, instead of a mere collection of pithy sayings and isolated, beautiful, but disconnected reflections. This was the only way of doing justice to an author, some of whose reasonings are out of date, but the spirit of whose main contention is eternally valid; a teacher of virtue and duty, who did not attempt to inculcate this or that individual virtue, but aimed at the formation of character and conditions in which right conduct would be inevitable, so that details might well be left to take care of themselves. If the modern world owes its delight in physical beauty, and much of its sense of the true in Nature and in Art, to Greece; its ideal of goodness, and practically all the spiritual elements in our thought and feeling, our conception of holiness, and every moral characteristic of civilisation and of culture, have come to us from the Orient. For the form and system of Ethics we may be indebted to the few Hellenic thinkers whose sublime intellects raised them above the phenomenal world into a clear atmosphere of ideas, always suffused with the light of truth and justice; but all the permanent and vital contents of Ethics came, living and pulsating, with their vitalising possibilities, both into that atmosphere and into our life of to-day, with the glow of dawn from the East. Indeed, the two cardinal ideas essential to all present and future moral systems—the sanctity of human life as such, and the absolutely universal authority and validity of moral law and obligation—are entirely absent from even the writings of Plato, the greatest of the Greeks. These two are among the most definite colours that the prism of modern thought has enabled us to single out in our perception of the pure white light, from the sun of righteousness, that shone on Sinai. They are specially characteristic of the Hebrew moral teaching which the three great religions—Judaism, Christianity and Islamism—have spread throughout the world.
