Well certainly I think we all can agree that there are other forces both known and unknown abetting the evolution of consciousness, than just reason. However, setting aside at present the unknown which is in the domain of metaphysics, I think we could all agree that the most fundamental instrument of evolution is biology. So this begs the question, if human reason is developing instrumentation to alter our very biology, and the biological mutations which are the result of this alteration, become the adaptive mechanism of the future evolution (of human consciousness), then the phenomena which emerges from the intervention of reason, becomes something greater than, the sum of its parts (e.g. reason) does it not?
