This thesis is about Ronald Dworkin’s conception of justice as equal respect and concern from which we study the interaction between its principles and the development of personal identity. The idea behind it is that justice as equal liberty involves a problem of commensurability : how do we ascertain that each individual really has an equal share of freedom? Our hypothesis is that the structure through which equal respect and concern is made tangible may have the side effect of dictating membership, whereby one’s identity is fused with his circumstances, on account of the comparison needed to evaluate what he is entitled to. This dynamic would result in a differentiation which weaken the political bonds within the community. Therefore, liberal equality should give education a special place, as a mean of developing agency and its resilience. Using as stepping stones the two principles of human dignity, we define what a liberal education would entail.
