Itzak bentov argues that consciousness is a continuum. Stones have it, but at a very unrefined level. Plants have it at a higher degree that stones. Bacteria, amoebas, and protozoa have it at a higher degree than plants. Then bugs et al. Animals have it at a higher degree than bugs. Primates and dolphins are animals with more than others. Then humans have it at a higher degree. So most things 'have conciousness' according to bentov, but some have higher refinement of conciousness' than others. Rather than saying some things have conciousness' and some don't, I agree with this approach.
