There is only you left on Earth, so what sort of life should you lead.

You are suddenly the last person on Earth and you
are wondering what sort of life you should lead.
You might think, 'I can now do what pleases me most.'
However what pleases you most is dependent on an overhanging
 'moral judgement' of what action is most pleasing.
If you then cry out to the emptiness  
and a voice (if it came back) calls, 'Do what pleases you most;
do what you prefer.' 
But I don't know what I prefer to do until I have decided what 
sort of life I now want to lead or how I should want this world 
to be. 
Since our preferences are shaped by moral explanations 
although you are alone on the planet, there seems 
to be little freedom. Next time round, stay away from philosophy.
