the key difference between me and Levi

Here you can read his interesting post on TOPOLOGICAL themes in his philosophy, which he says (and I hadn’t heard this before) that it’s been an interest of his since his high Lacanian days.

This is the real source of differences, when it comes down to it. Topology is something derivative for me, but for Levi it’s the very nature of things, which puts him quite a bit closer to DeLanda than I am. As for me, I’m a good old “actualist.” For me, all that exist are specific entities of a determinate nature, though they happen to be inaccessible to any direct contact by humans, animals, or anything else.

From this follows the aspects of my position towards which Levi has been perhaps the most cool: indirect/vicarious causation, and the fourfold structure in which real objects/qualities are accompanied by a separate pair of sensual objects/qualities.
