It is not because the truth is too difficult to see that we make mistakes... we make mistakes because the easiest and most comfortable course for us is to seek insight where it accords with our emotions - especially selfish ones.

Solzhenitsyn is diagnosing error as a moral and psychological choice rather than an intellectual limitation. People often claim that truth is obscure or inaccessible, but he argues that we miss it because we prefer conclusions that flatter our desires, loyalties, and self-interest. “Insight” becomes something we shop for—selecting interpretations that feel emotionally comfortable—rather than something we submit ourselves to. The quote fits his broader preoccupation with self-deception and the ways ideology and personal advantage can override conscience. It implies that clearer thinking requires ethical discipline: a willingness to endure discomfort, to question one’s motives, and to accept truths that may condemn or inconvenience us.
