ممنون من نظرات آقای هیوم را مستقیما از آثارشان نخواندم اما دوست داشتم اگر ممکن است لینکی در توضیح چرایی مطلق بودن اخلاق در دیدگاه هیوم بگذارید .آقای کوروش تنها نام چند کتاب را گفته بودند در حالیکه من بدنبال لینک اینترنتی چند صفحه یا مقاله هستم تا بتوانم با توجه به وقتم استفاده کنم .پیشاپیش سپاسگزار خواهم بود .

البته من همانطور که گفتم وجود حقایق اخلاقی آنچنان مطلب مهمی در اخلاق نیست.اگر علاقمند هستید از پایه مطالب کلی تر را مطالعه کنید برایتان سودمنتر خواهد بود.
اینهم مختصری از دیدگاه اخلاقی جناب هیوم:

Brief overview of Hume's ethics

Five important aspects of Hume's moral theory are the following.

First, Hume's approach to ethics could be called naturalistic, empirical, or experimental. There are a variety of reasons for this. Hume's ethics is part of his larger philosophical endeavor to explain naturalistically all aspects of human nature—not just what we can know of the world around us, but also how we make moral judgments and why we have religious beliefs. Hume's ethics relies on and reflects his philosophy of mind, which is empirical in its approach. He intends to use the same experimental method in analyzing human morality that he uses in analyzing human understanding. Hume treats ethics, together with psychology, history, aesthetics, and politics, as the subject of his “moral science.” Hume often seems more interested in explaining morality as an existing natural phenomenon than in setting out a normative ethical theory. Hume seeks to displace a priori conceptions of human nature and morality with an approach according to which everything about us is open to empirical investigation and to explanation in naturalistic terms. Hume often compares humans with other animals, tracing the bases of human morality to features we share with them. Hume talks about morality and virtue as independent of religion and the supernatural, and about moral action as part of the same physical world in which we reasonably talk of in terms of cause and effect (ECHU 61).

Second, according to Hume, moral judgments are essentially the deliverances of sentiment (ECPM 85). We recognize moral good and evil by means of certain feelings: the calm pleasure of moral approval or the discomfiting displeasure of moral disapproval, either of which may be felt in contemplating a character trait in oneself or another from an unbiased perspective (“the general point of view”). According to Hume, traits—be they feelings, motives, or abilities—that elicit our approval are those that are useful or agreeable to oneself or others; those that elicit our disapproval are those that are harmful or unpleasant for oneself or others. We call the traits that elicit our approval “virtues,” and those that elicit our disapproval “vices.” Hume assumes that we all have the same moral feelings, that is, that if we all take up the moral point of view, we will all agree in our approvals and disapprovals of various traits. The operation of our sentiments of moral approval and disapproval depend on sympathy, which allows the feelings of one person to be shared by others. Although Hume believes that only human beings experience moral sentiments, he believes that nonhuman animals also have sympathy, and thus share with us one of the essential foundations of morality.

Third, Hume's ethics contains an extensive and diverse set of virtues. In Hume's ethics, character traits are the primary object of moral assessment. Acts are judged derivatively, in relation to the traits assumed to cause them. In the Treatise, he divides virtues into the categories of natural virtues (e.g., beneficence and temperance) and artificial virtues (e.g., justice and fidelity to promises). Natural virtues are those traits that are useful or agreeable to people whether or not they are living in a large society, whereas artificial virtues are those traits that emerge as useful or agreeable in social groups that go beyond families or small communities, and in which social cooperation is needed among people with few or no personal ties. Natural virtues produce benefit or enjoyment with far greater reliability than artificial virtues do. Indeed, only natural virtues are characteristically pleasing on all occasions of their expression. Artificial virtues benefit people not consistently on each occasion, but rather through their wide-spread practice over time throughout a community (T 579–80).

Fourth, Hume provides only a limited (though not unimportant) role to reason in ethics. The principal role that Hume gives to reason in ethics is one of helping agents see which actions and qualities are genuinely beneficial or efficacious. Hume denies that reason itself sets the standard of morality, or sets forth certain ends as morally to be promoted. Reason, according to Hume, is a faculty concerned with truth or falsehood, both demonstrably in the realm of relations of ideas, or empirically in the realm of matters of fact. Reason makes inferences, but neither sets ends, nor motivates action. Our ends depend on what we desire, which depends on what we feel (with respect to pleasure and pain). “Reason, being cool and disengaged, is no motive to action, and directs only the impulse received from appetite or inclination, by showing us the means of attaining happiness or avoiding misery: Taste, as it gives pleasure or pain, and thereby constitutes happiness or misery, becomes a motive to action, and is the first spring or impulse to the desire and volition” (ECMP 88). Once feeling has established utility as one of the primary objects of morality, reason is essential to determine which character traits or modes and conduct conduce to it. This task is especially difficult with regard to questions of artificial virtues, such as justice, since so many people are involved, and since the social benefits of these virtues can be expected only from (possibly tong-term) collective action (ECPM 82-83). Reason has other roles related to morality, too. For example, Hume notes that in order to make a moral judgment, one must have in mind all the relevant facts, and apprehend all the relevant relations of ideas. This takes reason. The moral judgment itself, however, is not possible without sentiment, which takes in all the deliverances of reason and emerges with something beyond them: the sentiment of approval or disapproval.

Fifth, Hume takes morality to be independent of religion. In his ethical works, he clearly tries to ground morality in human nature, and to make a case for morality that stands just as well without a theistic underpinning as with one. He does not argue against belief in God in his ethical works, so much as for the irrelevance of God for morality. Moreover, by basing morality in sentiment, he excludes God as a moral assessor. In Dialogues Concerning Natural Religion he considers and refutes the main speculative arguments for the existence of God. In his A Natural History of Religion, he provides an account of how religion emerged from human nature within the human predicament.
