See David Kelley’s Evidence of the Senses, summarized here by Grames (written before Kelley’s break with Rand).
David Kelley didn’t break with Rand, he broke with Peikoff. He was at her funeral, and did the reading of Kipling’s If. Like him or lump him, he’s spent his life spreading her ideas. Here he is, just a couple weeks ago, working on the second part of the Atlas Shrugged movie series (second from left).
