if you have been assaulted by somebody you thought you could trust, how do you restore your sense of trust in the world or in people? And how do you … - Jon Krakauer

The more improbable the situation and the greater the demands made on [the climber], the more sweetly the blood flows later in release from all that tension. The possibility of danger serves merely to sharpen his awareness and control. And perhaps this is the rationale of all risky sports: You deliberately raise the ante of effort and concentration in order, as it were, to clear your mind of trivialities.

It would be easy to stereotype Christopher McCandless as another boy who felt too much, a loopy young man who read too many books and lacked even a modicum of common sense. But the stereotype isn't a good fit. McCandless wasn't some feckless slacker, adrift and confused, racked by existential despair. To the contrary: His life hummed with meaning and purpose. But the meaning he wrested from existence lay beyond the comfortable path: McCandless distrusted the value of things that came easily. He demanded much of himself — more, in the end, than he could deliver.

I don't know what God is, or what God had in mind when the universe was set in motion. In fact, I don't know if God even exists, although I confess that I sometimes find myself praying in times of great fear, or despair, or astonishment at a display of unexpected beauty. There are some ten thousand religious sects — each with its own cosmology, each with its own answer for the meaning of life and death. Most assert that the other 9,999 not only have it completely wrong but are instruments of evil, besides. None of the ten thousand has yet persuaded me to make the requisite leap of faith. In the absence of conviction, I've come to terms with the fact that uncertainty is an inescapable corollary of life. An abundance of mystery is simply part of the bargain — which doesn't strike me as something to lament. Accepting the essential inscrutability of existence, in any case, is surely preferable to its opposite: capitulating to the tyranny of intransigent belief. And if I remain in the dark about our purpose here, and the meaning of eternity, I have nevertheless arrived at an understanding of a few modest truths: Most of us fear death. Most of us yearn to comprehend how we got here, and why — which is to say, most of us ache to know the love of our creator. And we will no doubt feel that ache, most of us, for as long as we happen to be alive.
