This book is Joe Sachs’s translation of Metaphysics. Sachs’s translations bring distinguished new light onto Aristotle’s works, which are foundational to history of science. Sachs translates Aristotle with an authenticity that was lost when Aristotle was translated into Latin and abstract Latin words came to stand for concepts Aristotle expressed with phrases in everyday Greek language. By translating directly from the Greek, Joe Sachs’ translations avoid the latinized interpretations and thus come closer to offering Aristotle’s original thoughts to readers.
