How does Shakespeare exemplifies humanism and the Renaissance?

"Shakespeare was a humanist in everything he wrote." In an era preoccupied with religion, Shakespeare's plays and poetry are remarkably secular in subject matter and outlook, and Shakespeare seems to have been influenced by classical and Renaissance ideas about the importance of reason and of mankind and human individualism. "To thine own self be true," advises Polonius in Hamlet, a view of personal integrity that is essentially humanist in its stress on individualism rather than on conformity.
