Walt Whitman suggests ideal humanity based on his ideas of Christian God and the natural world. He himself is said to develope into his ideal. The contents of the ideal humanity are power, receptivity and love. Of three contents, he most emphasizes the individual power which can embody freedom and equality, democratic ideals. The godlike power can confront external tyrannies and extreme difficulties and conserve intrinsic individuality. The power can be strong to evil-doers, which means embracing rather than demarcating and excluding them. Receptivity is about embracing them. He acknowledges his own evils and so understands human evils. For him, evils can be changed into good energy. They are just debris in the flowing Universe or to thicken the plot in the human world. By enlarging the good, he makes evils meaningless. He teaches the reader to love human beings and nature. For him, love is especially for the weak. Charity and compassion is part of love. He gives himself to the weak, identifies with them, comforts them, ascertains their intrinsic values and urges them to live with strong power. Jesus Christ and the natural world embodies love. He calls the Christ his brother and comrade. By showing the model of his own life, he urges the reader to follow the ideal humanity.
