Ever since it was first published in 1740 in Amsterdam, it has enjoyed great renown and was eventually adopted as a basic text for ethical study. Throughout the long history of its publication, Mesillat Yesharim fell prey to many printers' errors. A breakthrough in its restoration occurred with the remarkable discovery by Ofeq Institute of a manuscript of an earlier version in the form of a dialogue, in the author's own hand. With this discovery and the aid of the first edition, Mesillat Yesharim was restored to its original state. Over the last decade, Ofeq Institute has published both versions of Mesillat Yesharim, the Dialogue and the Thematic, in Hebrew, twin editions. For although the two versions share the same content, they each supplement elements missing in the other. Of pivotal importance are the added chapters at the beginning of the Dialogue Version. These shed light on the profound nature of the work as a whole. It has now become common practice to study the two versions together, for the Dialogue Version reveals the brilliance of Mesillat Yesharim for all who seek to deepen their understanding of it. Ofeq has now published a new Hebrew-English edition of both versions in one volume utilizing an innovative facing-column format. With its completely new translation, invaluable commentary, Introduction and Epilogue (Bein Hamesilot), and extensive cross-referencing, this new edition allows the brilliance of the original to shine through. Available in two bindings: Hebrew-bound, i.e. right-to-left as with a standard Hebrew book, and English-bound, i.e. left-to-right as with a standard English book.

    He wrote vast volumes about animals. He described them, classified them, told us where and how they live and how they develop in the womb or in the egg. He founded a science. It can even be said that he founded science itself.In The Lagoon, acclaimed biologist Armand Marie Leroi recovers Aristotle’s science. He revisits Aristotle’s writings and the places where he worked. He goes to the eastern Aegean island of Lesbos to see the creatures that Aristotle saw, where he saw them. He explores Aristotle’s observations, his deep ideas, his inspired guesses—and the things he got wildly wrong. He shows how Aristotle’s science is deeply intertwined with his philosophical system and reveals that he was not only the first biologist, but also one of the greatest.The Lagoon is both a travelogue and a study of the origins of science. And it shows how a philosopher who lived almost two millennia ago still has so much to teach us today.
