Gabriel Marcel

"What must also be brought to light is the fact that love, in the fullest and most concrete sense of the word, namely, the love of one being for another, seems to rest on the unconditional: I shall continue to love you no matter what happens. This is at the very opposite pole from the conditional commitment which seems to presuppose a de facto if not a de jure stability only under the limited circumstances in which it is made. We should also say that love, far from merely requiring the acceptance of risk, demands it in a certain manner; love seems to be calling for a challenge to be tested because it is sure to emerge the conqueror."
