I DISCUSS KANT’S ARGUMENT FOR THE IRREDUCIBILITY OF BIOLOGY TO "MECHANISTIC" SCIENCE AS IT IS FOUND IN THE SECOND PART OF THE "CRITIQUE OF JUDGMENT", THE CRITIQUE OF TELEOLOGICAL JUDGMENT. THE PAPER CONSISTS OF TWO PARTS. IN THE FIRST I LAY OUT KANT’S POSITION, SHOWING THE RESPECT IN WHICH TELEOLOGY, FOR KANT, IS THE MARK OF THE LIVING. IN THE SECOND I TEST KANT’S VIEW AGAINST THE RECENT MECHANISTIC ANALYSIS OF TELEOLOGY PUT FORWARD BY ERNEST NAGEL IN "TELEOLOGY REVISITED" AND (...) SHOW THAT KANT’S POSITION MAY BE UNDERSTOOD AS A SERIOUS OBJECTION TO THE POSITION DEFENDED BY NAGEL. (shrink)
