Quote from Robert Burns

If we lie down in the grave, the whole man a piece of broken machinery, to moulder with the clods of the valley, be it so; at least there is an end of pain, care, woes, and wants. If that part of us called mind does survive the apparent destruction of the man--away with old-wife prejudices and tales. Every age and every nation has had a different set of stories; and as the many are always weak, of consequence they have often, perhaps always, been deceived. A man conscious of having acted an honest part among his fellow-creatures--even granting that he may have been the sport at times of passions and instincts--he goes to a great unknown Being, who could have no other end in giving him existence but to make him happy, who gave him those passions and instincts, and well knows their force. (Letter to Robert Muir, 7-March-1788)
