This is an English translation of Schelling's Ideas for a Philosophy of
Nature (first published in 1797 and revised in 1803), one of the most
significant works in the German tradition of philosophy of nature and
early nineteenth-century philosophy of science. It stands in opposition
to the Newtonian picture of matter as constituted by inert, impenetrable
particles, and argues instead for matter as an equilibrium of active
forces that engage in dynamic polar opposition to one another. In the
revisions of 1803 Schelling incorporated this dialectical view into a
neo-Platonic conception of an original unity divided upon itself. The
text is of more than simply historical interest: its daring and original
vision of nature, philosophy, and empirical science will prove absorbing
reading for all philosophers concerned with post-Kantian German
idealism, for scholars of German Romanticism, and for historians of
science.
