Law of contradiction.
Acceptance and reconciliation
In life, as one lives over time, one sees a law of contradiction seeming to take place. Simply put, one has to learn to live with contradictions often without resolution. This operates on many levels. Thesis, anti-thesis, both exist within the realm of possibility. The maker, purity of intent, both exist alongside sensual needs and pleasures. Good and bad exist within the same person.
When younger one looks for a system, a paradigm that will include all things. This always fails because we have no way of seeing the whole picture. Ideologies, “isms,” fall into this category. In physics you have the poles, plus and minus, combining to make the whole.
In the realm of ideas, existence, theories and the spirit, the only antidote to contradiction is acceptance and reconciliation. You just have to encompass both under a big umbrella.
