Answer :
The excerpt from The Death of Ivan Ilych that can be used as textual evidence to support a thesis statement on the theme of loneliness is ‘There was no deceiving himself: something terrible, new, and more important than anything before in his life, was taking place within him of which he alone was aware’.
The excerpt in "The Death of Ivan Ilyich" that starts with the sentence "There was no deceiving himself: something terrible, new, and more important than anything before in his life, was taking place within him of which he alone was aware." can be used as textual evidence to support a thesis statement on the theme of loneliness.
That excerpt narrates the fact that a very bad feeling was starting to take over Ivan from the inside but no one else but him seems to see or understand it. The sentence "That tormented Ivan Ilyich more than anything" explicitly suggests Ivan's loneliness in response to the matter. We can see that depression is being described, and the fact that no one seems to care makes it worse.
