IN offering this book to the English public, I have to discharge a two-fold duty. In the first place, I must thank my friend the Rev. PH. H. WICKSTEED, M.A., for his readiness to undertake the translation of my Lectures, and for the manner in which he performed his task. It was originally my intention to write the Lectures in English myself. But I was not long in perceiving that the execution of this plan would take more time than I could well spare, and that, after all, the product of my exertions would be unworthy to occupy its place in the Series for which it was destined. Under these circumstances, I considered it from the first as a great privilege that my friend WICKSTEED was willing to come to my aid; but only when the work was going on and when we were constantly discussing it together, I became fully aware how much reason I had to congratulate myself |
