Liberate yourself as far as you can, and you have done your part; for it is not given to every one to break through all limits, or,more expressively, not to every one is that a limit which is a limit for the rest. Consequently, do not tire yourself with toiling at the limits of others... He who overturns one of his limits may have shown others the way and the means; the overturning of their limits remains their affair.
