Causality, Chemistry, Catalyst

Kant's main variation on Hume's concept of Causality--that 'constant conjunction' is, more accurately, 'ordered succession'--accepts the Atomism of the latter, i. e. that such a succession, too, is a relation between two representations.  Now, while that Atomism might be suitable to Newtonian Mechanistic Physics, it seems inadequate to another Natural Science, namely Chemistry, which studies changes that ensue from the compresence  of several factors, e. g. of two elements and heat.  Accordingly, non-Atomistic patterns, such as Concrescence or Emergence, seem to better interpret 'chemical changes' than does Atomistic Causality.  Indeed, the event usually characterized as 'Gravity causing an apple to fall on Newton', can also be interpreted as the compresence of an apple-bearing tree, Newton, and gravitational pull, into which a gust of wind enters.  In those terms, the decisive factor is the gust of wind functioning as a 'catalyst'.
