Consider the notions of infinity and the finite. This pair of concepts embody both a contradictory and a complementary relationship. The two concepts compliment one another in that each makes the other more understandable through their contrast. They are contradictory in that each conveys a meaning that is 180 degrees out from the other.
The finite can only exist as a reduction of the infinite. That is, the finite is a subset of the infinite. Now consider an ocean and a wave. The wave can only exist as a subset of the ocean. The finite can never subsume the infinite and a wave can never subsume an ocean.
Let’s now think about “love” and “hate.” According to many spiritual traditions, love is the underlying dynamic of the universe. It is also said by many spiritual traditions that hate arises from fear and that fear is a corruption of love. The logic of the ocean and the wave can help us frame love and hate. It is far more likely that “love” is like the infinite or like an ocean because it is easy to see that “hate” is a more contracted expression than love. Thus, it seems appropriate to think of hate as a subset of love. A subset in the sense that hate arises from a corruption of love by fear that is engendered by spiritual ignorance (see my post The Nature of Evil).
Let’s end this brief discussion with the concepts of “good” and “evil.” I would argue that, like love, good is ontologically superior to evil. Good is the value field in which evil arises just as an ocean is the field in which waves arise. Thus, we can view evil as a subset of good. The infinite, waves, love and good can be thought of as all-inclusive fields in which contradictory and complimentary factions arise. These factions serve the function of making experience possible from the possibilities opened up through the contrasts they provide. After all, you could not experience temperature in the absence of the contrast provided by hot and cold.
