How we cite our quotes: (Chapter.Paragraph)
Quote #1
I jump up: it would be much better if I could only stop thinking. Thoughts are the dullest things. (22.34).
One of Antoine's biggest wishes is that he could learn to stop thinking altogether. After all, his thoughts aren't very cheery, and it's very difficult to not think about something that's bothering you.
Quote #2
I have no troubles, I have money like a capitalist, no boss, no wife, no children; I exist, that's all. And the trouble is so vague, so metaphysical that I am ashamed of it. (24.36)
One of the reasons Antoine spends so much time hanging out and thinking about existence is because he has all the money he needs to never work again. For this reason, he has trouble justifying his existence, since there's really no reason for him to get up in the morning apart from whatever reason he invents for himself.
Quote #3
I am in the midst of things, nameless things. (24.296)
One of the things that troubles Antoine most is the question of what kind of world exists beneath the one created by human language and human concepts. You, for example, might see a table and think, "table." But the truth is that you're staring at a bunch of dead physical material shaped like something you recognize. The matter, though, doesn't care what you think it is. It's just there and it could just as easily be a pile of wood as it could be a table.
