An Enquiry Concerning the Principles of Morals

Question

Why is Hume's assertion, made during the Enlightenment, that sentiment rather than reason forms the basis of morals, significant or potentially controversial for his time?

Synthesized answer

Hume's assertion that sentiment, rather than reason, forms the basis of morals was significant and potentially controversial in his time because it challenged the prevailing philosophical view that morality was derived from reason [1]. The ancient philosophers, while sometimes stating virtue conformed to reason, generally considered morals to stem from taste and sentiment [1]. Hume argues that while reason can inform us of the tendencies of actions, it is insufficient on its own to produce moral blame or approbation [5]. He posits that sentiment, specifically a feeling for the happiness of mankind and resentment of misery, is necessary to prefer useful over pernicious tendencies [2, 5].

This perspective implies that moral distinctions are not universally applicable to all rational beings, but are founded on the particular fabric and constitution of the human species, akin to the perception of beauty and deformity [1]. Hume further suggests that moral decisions involve a partition between the faculties of understanding and sentiment [2]. Without sentiment, reason alone cannot influence conduct or behavior, as it merely discovers truths that, if indifferent, do not create desire or…

ble of like impressions. The only way, therefore, of converting an antagonist of this kind, is to leave him to himself. For, finding that nobody keeps up the controversy with him, it is probable he will, at last, of himself, from mere weariness, come over to the side of common sense and reason. There has been a controversy started of late, much better worth examination, concerning the general foundation of Morals; whether they be derived from Reason, or from Sentiment; whether we attain the knowledge of them by a chain of argument and induction, or by an immediate feeling and finer…
Passage [6]
e a SENTIMENT should here display itself, in order to give a preference to the useful above the pernicious tendencies. This SENTIMENT can be no other than a feeling for the happiness of mankind, and a resentment of their misery; since these are the different ends which virtue and vice have a tendency to promote. Here therefore REASON instructs us in the several tendencies of actions, and HUMANITY makes a distinction in favour of those which are useful and beneficial. This partition between the faculties of understanding and sentiment, in all moral decisions, seems clear from the…
Passage [238]
these affections, but the original fabric and formation of the human mind, which is naturally adapted to receive them? The end of all moral speculations is to teach us our duty; and, by proper representations of the deformity of vice and beauty of virtue, beget correspondent habits, and engage us to avoid the one, and embrace the other. But is this ever to be expected from inferences and conclusions of the understanding, which of themselves have no hold of the affections or set in motion the active powers of men? They discover truths: but where the truths which they discover are…
Passage [10]
ures only the cool assent of the understanding; and gratifying a speculative curiosity, puts an end to our researches. Extinguish all the warm feelings and prepossessions in favour of virtue, and all disgust or aversion to vice: render men totally indifferent towards these distinctions; and morality is no longer a practical study, nor has any tendency to regulate our lives and actions. These arguments on each side (and many more might be produced) are so plausible, that I am apt to suspect, they may, the one as well as the other, be solid and satisfactory, and that reason and sentiment…

interests which may be proposed; these, on many occasions, are doubtful, and subject to great discussion and inquiry. The object of municipal laws is to fix all the questions with regard to justice: the debates of civilians; the reflections of politicians; the precedents of history and public records, are all directed to the same purpose. And a very accurate REASON or JUDGEMENT is often requisite, to give the true determination, amidst such intricate doubts arising from obscure or opposite utilities. But though reason, when fully assisted and improved, be sufficient to instruct us in…
