Fyodor Dostoevsky's 'The Idiot' introduces Prince Lev Nikolayevich Myshkin, a compassionate and naive protagonist who returns to Russia after years in a Swiss sanatorium. Hailed as one of literature's most profound examinations of a truly good man, Myshkin attempts to live virtuously amidst the moral decay and ruthless ambition of St. Petersburg's high society. His innocence and idealism clash with the greed, passion, and intrigue surrounding him, particularly in his relationships with the captivating Nastasya Filippovna and the beautiful Aglaya Ivanovna. The novel explores themes of purity, love, redemption, and the impossibility of maintaining Christ-like virtues in a fallen world, culminating in a tragic and unforgettable climax that questions the nature of sanity and the power of goodness.
