Justify the complexity of the human mind with reference to Jimmy Porter.

Jimmy Porter is a character of immense psychological complexity and interest. He dominates the play through the power of his anger and language. He unleashes his invective on what he calls the Establishment (those "born" to power and privilege), the church as part of the Establishment, and his loved ones. Osborne describes him as "a disconcerting mixture of sincerity and cheerful malice, of tenderness and freebooting cruelty; restless, importunate, full of pride, a combination which alienates the sensitive and insensitive alike." Critic Harold Ferrar assessed him as a man of decency and charity who is "one of life's beautiful losers."
