Abstract
The argument of this paper is threefold: (a) Charles Bonnet’s naturalization of the principle of perfectibility (in the wake of Rousseau) is one example of a more general philosophical operation to be found in his writings: to naturalize the metaphysical while insisting upon its minimal difference from the material and so to generate an immaterialism that looks like a materialism; (b) this operation structures Bonnet’s entire palingenetic project which can be defined as an ‘anomalous naturalism’; (c) variants of this anomalous naturalism were available to German philosophers during the last decades of the eighteenth century – philosophers such as G. E. Lessing, F. H. Jacobi and J. G. Herder – and, to this extent, their writings also display traits of this ‘anomalous naturalism’.
