Democracy is based on two values: equality and freedom. However, equality and freedom are not absolute values because there is no abstract principle (including the principles of freedom and equality), which would not allow exceptions to the application. But the difference between the rule and the exception is that an exception must be justified. Where freedom is the rule, the limits of freedom must be justified, and where equality is the rule, the unequal treatment must be justified. In this presentation two topics will be discussed. First, some examples from the sphere of education, which can be understood as justified limits of freedom, where freedom is a rule. Second, one (for the understanding of democratic education important) example, where unequal treatment consensus that the limits of freedom, which are considered as a rule, eligible. The second part is the subject of analysis, only one, a democratic education to understand the important case where the equality rule and should therefore be discriminatory treatment (as an exception) is justified. It is a well known idea of equal educational opportunities.
