Companionship

We like companionship, see, but we can't stand to be around people for very long.
("Into the wild", J. Krakauer)

Intelligent companionship

It is true that I miss intelligent companionship, but there are so few with whom I can share the things that mean so much to me, that I have learned to contain myself.
("Into the wild", J. Krakauer)

Relieved

[...] he was relieved as well - relieved that he had again evaded the impending threat of human intimacy, of friendship, and all the messy emotional baggage that comes with it.
("Into the wild", J. Krakauer)

A world

[...] a world of abstraction and security and material excess, a world in which he felt grievously cut off from the raw throb of existence.
("Into the wild", J. Krakauer)

Make sense

Sometimes he tried too hard to make sense of the world, to figure out why people where bad to each other so often.
("Into the wild", J. Krakauer)

Eternity

It was the masterful and incommunicable wisdom of eternity laughing at the futility of life and the effort of life.
("Into the wild", J. Krakauer)

None of that matters

I don't want to know what time it is. I don't want to know what day it is or where I am. None of that matters.
("Into the wild", J. Krakauer)
