Solipsism

The view, or sometimes just the haunting suspicion, that the only thing one can be sure exists is one's own mind — that other people, the external world, and any shared sense of reality might be inaccessible or even illusory. In its strict philosophical form solipsism is rarely defended, but as a felt condition it shows up everywhere: in the worry that language never quite carries your inner experience across to anyone else, that you are sealed inside your own head and only ever approximating contact with others. A recurring anxiety in David Foster Wallace's fiction, and the problem that drew him to Wittgenstein, whose later philosophy reframes meaning as something constituted between people rather than locked inside them.
