There is no opportunism in the coming together of oxygen and hydrogen to generate water. The fact of waterness is intrinsic to the nature of reality . In the simplest manifestation of life there is not a consciousness guiding and staying the course which is most opportune. Selection and adaptation in their most impassive self are the arbiter for life and death. Throughout the food chain, 3-4 eons on this planet, the opportunity to survive and procreate, is all there was that living reality could offer.
Consequently opportunism is the agency that saturates the doings of life.
Opportunism is and remains the most innate of our drives and it is more and more adopted by individuals of the Homo Sapien population as a totally legitimate expression of the ego. Capitalism is the most recent incarnation of opportunism , and there are its strengths and limitations. The evolution of man and minds will be the story of post opportunism or it will be a story of sorrow, sadness, and suffering.
