Note 317 — Chapter IV

Sir James Mackintosh was so struck by the stationary character of moral principles, that he denies the possibility of their advance, and boldly affirms that no further discoveries can be made in morals: ‘Morality admits no discoveries…. More than three thousand years have elapsed since the composition of the Pentateuch; and let any man, if he is able, tell me in what important respect the rule of life has varied since that distant period. Let the Institutes of Menu be explored with the same view; we shall arrive at the same conclusion. Let the books of false religion be opened; it will be found that their moral system is, in all its grand features, the same…. The fact is evident that no improvements have been made in practical morality…. The facts which lead to the formation of moral rules are as accessible, and must be as obvious, to the simplest barbarian as to the most enlightened philosopher…. The case of the physical and speculative sciences is directly opposite. There the facts are remote and scarcely accessible…. From the countless variety of the facts with which they are conversant, it is impossible to prescribe any bounds to their future improvement. It is otherwise with morals. They have hitherto been stationary; and, in my opinion, they are likely for ever to continue so.’ Life of Mackintosh, edited by his Son, London, 1835, vol. i. pp. 119–122. Condorcet (Vie de Turgot, p. 180) says, ‘La morale de toutes les nations a été la même;’ and Kant (Logik, in Kant's Werke, vol. i. p. 356), ‘In der Moral-philosophie sind wir nicht weiter gekommen, als die Alten.’
