The aim of this paper is to propose a psychological interpretation for the expression 'limits', often used in moral education. We analyse two dimensions of limits. The first: limits as restriction of freedom, so, limits as duty. The second: limits as overcoming, so as ideals, as self-improvement, as virtues. We discuss both dimensions in moral and psychological terms, and we try to show that they are intimately associated.
