Plato believed that our souls were once split in half and the quest for finding the right person with whom to spend one’s life was that of (literally) finding “your other half.” In contrast, Jean-Paul Sartre, a French existentialist philosopher, would admonish you that the person you choose as your mate will be the right person because you have chosen this person, not because there is a cosmic truth that says so.
Existentially, truth is where you hang your hat; and that is clearly a lot of responsibility to carry. You can accept responsibility and live accordingly or you can retreat from it, not act, procrastinate, hold out for ultimate truth, and succeed only in defining yourself as a disappointed dream, hope, wish, or expectation. The relative truth is that you will find “the one” only by taking the plunge into reality.
