 Some stuff ontologists eliminate concrete things altogether. There is only stuff, objects being accidental phases of objectively non-objectual stuff. Alternatively, concepts are thought of as ‘cookie-cutters’, which conventionally carve pseudo-objects (cf Dummet 1981, chap 16) out of the amorphous world-blob, which either is not itself an object (Sidelle 1989), or is the only object there is (Horgan &amp; Potrč 2000,  2008).[22]
