 This is Spinoza’s thesis of panpsychism, or universal mindedness (more precisely, universal at least for all “individuals” or composite entities [E2def; G/II/100]). Panpsychism follows because all it takes for there to be a finite “mind” in Spinoza’s view is that there be some “part” of the omniscient divine intellect – some component idea of it – that represents some discernible bit of being. So not only is there nothing more to minds than ideas (2.1.1), there is nothing more to creaturely minds than God’s ideas.
