The essence of the quote highlights the idea that ignorance does not absolve one of guilt. The protagonist's declaration of innocence rests on his lack of knowledge, which raises deeper moral questions about responsibility and awareness. Simply claiming innocence by stating "I did not know" does not erase the underlying actions or choices that may have led to harm or wrongdoing.

Kundera suggests that an individual's belief and the insistence on their own innocence can blind them to their moral failings. By focusing solely on their good intentions and self-perception, they may fail to see the profound implications of their actions. This raises the question of whether one can truly maintain a clear conscience while neglecting the realities and consequences of their beliefs and decisions.
