Boagie, I'll try not to be lured into to many comments, but I figure this might help.
In evertything that exists there is consciousness because consciouss is the possibility to be acted upon. Even on vacuüm can be acted in the sense that the vacuüm cannot exist where matter exists. Consciousness, therefore, exists universally. Only something which has the possibility to create a 'database' of past actions upon itself has the possibility to come to 'reason'. To the best of my knowledge only matter has the possibility to create such a 'database'. That is why only material things can come to self-consciousness. Self-consciousness is the cognitive realisation of being acted upon by the comparrison of different 'states' the material thing has been in by use of the 'database'.
Consciousness is the reaction to being acted upon, the growing of grass due to water and sunlight for instance, or the 'carrying' of one rock by another which lies below it. Self-consciousness is the possibility of realisation of being acted upon. Because of self-consciousness the object responds to being acted upon in a second manner which has no physical causal relation to being acted upon; the drive to re-act. By such a drive the object, if it has the means to do so can re-act. The possibility to do so lies in self-consciousness, the 'database'. It creates the possibility to re-act by the non-physical 'movement' created in the database by the physical movement.
Hope this helps.
