The paper attempts to reconstruct the intellectual framework of British liberal tradition focusing on two major problems of it, namely the problem of justice and that of political liberty. The liberal interpretation of justice is meant to tolerate all possible individual views of good life, consequently it cannot be established on one of them. This means that the interpretation of justice shouldn’t be derived from some philosophy, as any interpretation has its basis in the political tradition of modernity. Consequently democracy always must have priority to philosophy (R. Rorty). On the matter of political liberty, Isaiah Berlin defends a “negativeâ€ concept of freedom, the freedom of choice without any pressure, while Ch. Taylor sustains the Positive one. The debate between defenders of negative and positive freedom seeks the answer for a question formulated for the first time by John Stuart Mill: why individuals - even if they are free - act usually rational?
