Abstract: Moliere is a French 17th-century comeliest of classical school.He inherited the tradition of fighting against feudalism and church from humanists in renaissance,being more liberal.He stuck to his liberal stand,ruthlessly exploded aristocrats' decadency and monks' hypocrisy,and made enlightening mockeries of bourgeois' greed,blindness,and vanity,and offers sincere praise and affirmation to lower working class.This kind of liberal writing stand comes not only from his inheritance of traditions,but also from his understanding of people after long years' stay with the population.
