As far as my simple self could deduce from Voltaire’s Candide, Pangloss and Martin are as different as they are wise when it comes to the brightness or, in Martin’s case, the darkness with which they view the world.
Pangloss is evidently a man of knowing and has put much thought into his philosophy that “everything is for the best in the physical as well as the moral universe and nothing could be otherwise…”Quite the optimist, he went about life accepting things the way they were, putting up little fight and attributing everything to the will of God or whatever higher power runs this universe (fate). I’d like to think that Pangloss even looked forward to living life, gathering experiences even if they weren’t exactly ideal. Martin on the other hand, finds life very depressing what with having no one to love and nothing to look forward to; he sees no goodness in his fellow man and no happiness in any situation and often expresses exasperation with life. The interesting thing about him however is that he carries still this energy, an angry passion if you will, to live as well as he can (i.e. Martin decides to hang around with Candide because he has nothing to his name while Candide is flowing with riches and people treat the rich much better than those who have none); he’s actually a dark version of a realist, I think.
Personally, I find Martin to be a much better companion to be with for rather than just placidly allow things to run way they do, he decides to take action and make things better in spite of his supposedly being fed up with the way the universe is.
