Mandatory

In fact, mandatory

I believe that despite the enormous odds which exist, unflinching, unswerving, fierce intellectual determination, as citizens, to define the real truth of our lives and our societies is a crucial obligation which devolves upon us all. It is in fact mandatory.

If such a determination is not embodied in our political vision we have no hope of restoring what is so nearly lost to us — the dignity of man.
