If we think of the future as a multiplicity of possibilities, or, more accurately, of the present moment as a vantage point which looks out over a horizon of undetermined possible futures, and if, moreover, we posit that we have the capacity to exercise what is called “Will” —
Will == the future tense of the verb “To Be”, understood as the present manifestation of a future existence
— and if we note that “decision” is related to words like “incision” or even “scissors” and thus rooted in something that means “to cut” (as a quick check of any dictionary will confirm) — then a de-cision is a cutting off of one possible future from all the others, by an act of “will” which can only be brought to bear when that “will” is “present.”
Understood in this way, decisions — that is, intentional acts of will which are determinative for the future — seem to be relatively rare among humans. Why? Perhaps it is because of the felt sense that taking responsibility for narrowing one’s options (shrinking that universe of possible futures) is frightening?
