‎First edition of Kraft’s paper on contradictions in traditional theories of matter and composite substances. Kraft argues that the traditional physics and metaphysics is filled with contradictions, particularly regarding the divisibility of matter, the nature of space and time and the structure of reality.

The present paper is a fine example of 18th-century Enlightenment debates on the nature of matter, space and time,‎
