The only real question about all this finitude is whether we’re willing to confront it or not. And this, for Heidegger, is the central challenge of human existence: since finitude defines our lives, he argues that living a truly authentic life—becoming fully human—means facing up to that fact. We must live out our lives, to whatever extent we can, in clear-eyed acknowledgment of our limitations, in the undeluded mode of existence that Heidegger calls “Being-towards-death,” aware that this is it, that life is not a dress rehearsal, that every choice requires myriad sacrifices, and that time is always already running out—indeed, that it may run out today, tomorrow, or next month. And so it’s not merely a matter of spending each day “as if” it were your last, as the cliché has it. The point is that it always actually might be. I can’t entirely depend upon a single moment of the future. Obviously, from any ordinary perspective, this all sounds intolerably morbid and stressful. But then, to the extent that you manage to achieve this outlook on life, you’re not seeing it from an ordinary perspective—and “morbid and stressful,” at least according to Heidegger, are exactly what it is not. On the contrary, it’s the only way for a finite human being to live fully, to relate to other people as full-fledged humans, and to experience the world as it truly is. What’s really morbid, from this perspective, is what most of us do, most of the time, instead of confronting our finitude, which is to indulge in avoidance and denial, or what Heidegger calls “falling.” Rather than taking ownership of our lives, we seek out distractions, or lose ourselves in busyness and the daily grind, so as to try to forget our real predicament. Or we try to avoid the intimidating responsibility of having to decide what to do with our finite time by telling ourselves that we don’t get to choose at all—that we must get married, or remain in a soul-destroying job, or anything else, simply because it’s the done thing. Or, as we saw in the previous chapter, we embark on the futile attempt to “get everything done,” which is really another way of trying to evade the responsibility of deciding what to do with your finite time—because if you actually could get everything done, you’d never have to choose among mutually exclusive possibilities. Life is usually more comfortable when you spend it avoiding the truth in this fashion. But it’s a stultifying, deadly sort of comfort. It’s only by facing our finitude that we can step into a truly authentic relationship with life.
