For Kant, to make public use of the reason consists of the fact of the individual independently to reveal, ahead of everything what it is and it composes the public being, its point of view in relation to all and any question that if develops inside of the public scope. For it, the individual that does not make public use of its reason, denies itself exactly the clarification. to deny itself the clarification condition is to renounce the proper freedom. A man without a doubt can, in what he respects its person, and exactly thus for some time, in the part that charges to it, to postpone the clarification (Aufklrung). But to renounce it, wants exactly for itself wants still more for its descent, means to wound and to trace to the feet the sacred rights of the humanity (Ibidem, p.110).
Without a doubt, the right greater of which the man deprives itself, when postponing the clarification, that is, to the life in the condition of the irrationality: it is the freedom. Kant, here, wants to point this exactly. For it, when the man accepted its condition of minority, that is, an irrationality condition front the world, and does not have courage to make use of its proper agreement, this is denying itself exactly one of the greaters right of the humanity: the freedom. Although Kant in this assay does not deepen the freedom concept? what he makes in the Critical one of the Practical Reason? one understands that, as it speaks in a iluminista perspective, here the concept freedom this related to the thought freedom.
