My interest in this theme of Leibniz goes back to a time when I began exploring generalized measures of determination and qualitative analogues of differential calculus — doctrines of absolute determinism or predestination had long ago loosened their hold on my mind — but a comment on my recent posting prompts me to add the following clarification.
I tend to read theological visions metaphorically, more in axiological and teleological veins. So I take Leibniz as presenting an ideal limit case of a perfect information cybernetic system — how the universe would look to an ideal observer, from a God’s Eye View. I do not know if it is possible to imagine such a point of view within the bounds of logic, but Leibniz seems to think God at least can have his cake and eat it, too:
There must therefore be no doubt that effects follow their causes determinately, in spite of contingency and even of freedom, which nevertheless exist together with certainty or determination.
