(An Enquiry Concerning The Principles Of Morals, 1751)
The foundation of Diogenes’s conduct was an endeavour to render himself an independent being as much as possible, and to confine all his wants and desires and pleasures within himself and his own mind: The aim of Pascal was to keep a perpetual sense of his dependence before his eyes, and never to forget his numberless wants and infirmities. The ancient supported himself by magnanimity, ostentation, pride, and the idea of his own superiority above his fellow-creatures. The modern made constant profession of humility and abasement, of the contempt and hatred of himself; and endeavoured to attain these supposed virtues, as far as they are attainable. The austerities of the Greek were in order to inure himself to hardships, and prevent his ever suffering: Those of the Frenchman were embraced merely for their own sake, and in order to suffer as much as possible. The philosopher indulged himself in the most beastly pleasures, even in public: The saint refused himself the most innocent, even in private. The former thought it his duty to love his friends, and to rail at them, and reprove them, and scold them: The latter endeavoured to be absolutely indifferent towards his nearest relations, and to love and speak well of his enemies. The great object of Diogenes’s wit was every kind of superstition, that is every kind of religion known in his time. The mortality of the soul was his standard principle; and even his sentiments of a divine providence seem to have been licentious. The most ridiculous superstitions directed Pascal’s faith and practice; and an extreme contempt of this life, in comparison of the future, was the chief foundation of his conduct.
In such a remarkable contrast do these two men stand: Yet both of them have met with general admiration in their different ages, and have been proposed as models of imitation. Where then is the universal standard of morals, which you talk of? And what rule shall we establish for the many different, nay contrary sentiments of mankind?
An experiment, said I, which succeeds in the air, will not always succeed in a vacuum. When men depart from the maxims of common reason, and affect these artificial lives, as you call them, no one can answer for what will please or displease them. They are in a different element from the rest of mankind; and the natural principles of their mind play not with the same regularity, as if left to themselves, free from the illusions of religious superstition or philosophical enthusiasm.
