John Stuart Mill (1806-1873) At the present period, however, this influence was only one among many which were helping to shape the character of my future development: and even after it became, I may truly say, the presiding principle of my mental progress, it did not alter the path, but only made me move forward more boldly, and, at the same time, more cautiously, in the same course. The only actual revolution which has ever taken place in my modes of thinking, was already complete. My new tendencies had to be confirmed in some respects, moderated in others: but the only substantial changes of opinion that were yet to come, related to politics, and consisted, on one hand, in a greater approximation, so far as regards the ultimate prospects of humanity, to a qualified Socialism, and on the other, a shifting of my political ideal from pure democracy, as commonly understood by its partizans, to the modified form of it, which is set forth in my “Considerations on Representative Government.”

Note from KBJ: How is it possible to move forward both "boldly" and "cautiously"?
