Shakespeare, William (1564-1616), English playwright and poet, recognized in much of the world as the greatest of all dramatists. Shakespeare s plays communicate a profound knowledge of the wellsprings of human behavior, revealed through portrayals of a wide variety of characters. His use of poetic and dramatic means to create a unified aesthetic effect out of a multiplicity of vocal expressions and actions is recognized as a singular achievement, and his use of poetry within his plays to express the deepest levels of human motivation in individual, social, and universal situations is considered one of the greatest accomplishments in literary history
