J. J. ROUSSEAU. 'Freue dich, höchstes Geschöpf der Natur, du fühlest dich fähig CENERAL PREFACE. THIS work takes its name from the essays occupying the first seventy pages of the book; but the later essays, as showing the nature of those parts of the universe which lie nearest to us, are properly included under the same title. It will be seen that my views respecting the interesting question of life in other worlds have changed considerably since I wrote the work bearing that title. I still consider that work a sound exposition of the theory of the plurality of worlds, though I consider that the weight of evidence favours my theory of the (relative) paucity of worlds. RICHD. A.
