ABSTRACT
Baruch Spinoza is man and philosopher, therefore, he will not abdicate from his citizenship. This social condition is a mediation to guarantee human existence. Spinoza will try to find out how a man may be free and happy. This is not as yet, a radical plan, but only a possibility, within a very positive and circumstancial society which, nevertheless, shows a strong tendency to establish a general social system. Spinoza imagines a society not so much to develop the human being but, more to allow the individual to develop, annulling the possibility of restraining his free mind and expression. The certainty, however, is not the best, as, in agreement with the Jewish philosopher, society stands over a voluntary pact and not over the consistent roots of understanding, being understanding provided with the ontological-logical certainty.
