One of the main characteristics of the Renaissance was its break with the attitude towards life of mediaeval society. The new Hellenistic, classical, humanistic spirit taught the Renaissance man that, far from being a groveling worm, he was a glorious creature capable of infinite individual development in a world which was his to interrogate, explore, and enjoy. The Renaissance exalted the human element, stressed the importance of human interests, and asserted the dignity of man—a trend which may be noted in most authors of the period. Rabelais portrays his heroes as giants, to whom nothing seems impossible, and places no limitations on their actions. Shakespeare writes: “What a piece of work is a man! How noble in reason! how infinite in faculty! in form, in moving, how express and admirable! in action how like an angel, in apprehension, how like a god! the beauty of the world! the paragon of animals!” Viewed from the standpoint of a social behaviorist, the Renaissance teaches mediaeval man, whose interests as an individual were completely subordinated to his function as an element in a feudalistic social unit, that it is possible and right for him to assert and realize self. Social conformity is no longer the only possible relation between man and the world about him. Therefore, the Renaissance man, more energetic and enthusiastic than his mediasval forefather, takes pleasure in a certain spirit of opposition to supposed human and known social limitations; he glories in nonconformity, he rejoices in isolation and in standing up against society and in consciously not doing that which he knows the society he lives in expects him to do. “To brave the disapproval of men is tonic. … Conflict is a necessity of the active soul.” In Spain, as elsewhere, the Renaissance exerted the same influence and a like need for self-expression was felt. Let us then examine the state of mind of Calderonian characters, who, living in the seventeenth century, should by then be well imbued with Renaissance thought, in an effort to determine the fundamental psychological needs underlying their urge towards self-realization.
