The difference between objective and subjective reduces to aspects of overwhelmingly linear or nonlinear nature. I abandoned this type of definition because it handled Cs as a thing, even if it was a functional object. It lead to a 'pansensitivity', an improved name for the maligned panpsychism. One cannot see a separate 'quality' from its substrate. Something like a transition to 'I myself'.
Life is a complexity level of processes, bound to complexities of diverse structural development.
Consciousness, if not restricted to human features, extends in first approach over the animal kingdom, in decreasing complexity down to the one-cell creatures which sense and respond just well to their level of lifestyle. Below that viruses exercise adaptability, response, with continuation in molecules, called reactivity. I referred to this above as pansensitivity, the high level complexity of which grows into mental etc. The neuronal brain is the material tool operating in the cooperation of the mind. As HM pointed out, we have no means to objectify experience, only the physically accessible aspects of it.
