Not as though you had thousands of years to live. Death hangs over you. While you still live, while you can, be good.
Not as though thou hadst thousands of years to live. Death hangs over thee: whilst yet thou livest, whilst thou mayest, be good.
Within ten days, if it happens, you could be seen as a god by the same people who would think of you as no better than an animal or an ape if you went back to your old beliefs and stopped honoring reason.
Within ten days, if so happen, thou shalt be esteemed a god of them, who now if thou shalt return to the dogmata and to the honouring of reason, will esteem of thee no better than of a mere brute, and of an ape.
