Epictetus In his
Discourses,
Epictetus employs the analogy of the human foot to elucidate the moral significance of duty: "Do you not know, that as a foot is no longer a foot if it is detached from the body, so you are no longer a man if you are separated from other men." Just as a human foot may sometimes get dirty or pierced by thorns in service to the body, individuals must also fulfil their roles, even if it entails facing sickness, perilous journeys, or premature death. Epictetus states, "It is your duty then, since you are come here, to say what you ought, to arrange these things as it is fit."
Marcus Aurelius Marcus Aurelius extensively discusses duty in his
Meditations, in a way that can be summarised using a key section from Book VIII:It is thy duty to order thy life well in every single act; and if every act does its duty, as far as is possible, be content; and no one is able to hinder thee so that each act shall not do its duty.- But something external will stand in the way.- Nothing will stand in the way of thy acting justly and soberly and considerately.- But perhaps some other active power will be hindered.- Well, but by acquiescing in the hindrance and by being content to transfer thy efforts to that which is allowed, another opportunity of action is immediately put before thee in place of that which was hindered, and one which will adapt itself to this ordering of which we are speaking.Similar to Epictetus, he emphasises the importance of duty for humans beings in their social dimension, but goes further by grounding duty in rationality. Marcus traces the origins of social obligation through a logical progression, viewing duty as stemming from the shared human capacity to reason: "which commands us what to do, and what not to do; if this is so, we are fellow-citizens; if this is so, we are members of some political community." This connection between reason and duty is highlighted too in Book VI, where he states: "I do my duty: other things trouble me not; for they are either things without life, or things without reason, or things that have rambled and know not the way." In fact, earlier in the
Meditations,
Marcus expresses concern about the decline of cognitive abilities with age as it affects the fulfilment of duty, noting that "the conception of things and the understanding of them cease first," which weakens "the power of making use of ourselves, and filling up the measure of our duty." He also urges readers to derive their sense of duty from within, rather than from external pressures, encouraging them to "stand erect; not be kept erect by others" and to "Labour not unwillingly, nor without regard to the common interest". Marcus repeatedly comes back to duty as a concept grounded in the human mind, but he does not ignore its social component, advising the reader to accept help, just as a lame solder ought to when fulfilling his duty to climb the battlements during a siege.
Nietzsche Friedrich Nietzsche is among the fiercest critics of the concept of duty. "What destroys a man more quickly", he asks, "than to work, think, and feel without inner necessity, without any deep personal desire, without pleasure—as a mere automaton of 'duty'?". Nietzsche claims that the task of all higher education is "to turn men into machines". The way to turn men into machines is to teach them to tolerate boredom. This is accomplished, Nietzsche says, by means of the concept of duty. The writings of
Arthur Schopenhauer, including
On the Basis of Morality, greatly influenced Nietzsche. These influences led Nietzsche to undertake a series of inversions, challenging the idea that morality stemmed from "compassion or sympathy." Instead, Nietzsche asserted that morality was rooted in life's self-overcoming through the
will to power. As part of these inversions, Nietzsche explored concepts like "duty" and "pity", previously discussed by
Immanuel Kant and Schopenhauer respectively.
Ayn Rand Ayn Rand, a youthful admirer of Nietzsche, anchored her morality against Kant's notion of duty. "In a
deontological theory, all personal desires are banished from the realm of morality; a personal desire has no moral significance, be it a desire to create or a desire to kill. For example, if a man is not supporting his life from duty, such a morality makes no distinction between supporting it by honest labor or by robbery. If a man wants to be honest, he deserves no moral credit; as Kant would put it, such honesty is 'praiseworthy,' but without 'moral import.'" ==See also==
