I believe so. A challenge here is what do you mean by consciousness and how would this relate to a spectrum of consciousness in order to be inclusive to all particles and organisations of matter/energy.
Another aspect here is that all particles are also energy, vibrating at different frequencies so that may be helpful in describing consciousness and freewill. As human beings I think we can all agree that there are times when we are more conscious and more free, how does this relate to other life and things?
