This online colloquium has been established to discuss Arash Abizadeh’s recent book, Hobbes and Two Faces of Ethics. We began with an introduction to the text by Professor Abizadeh and a response from Sandra Field. We now have a response from Michael LeBuffe (Otago), which will be followed by one from Daniel Eggers and then a reply by Arash Abizadeh. Many thanks to Cambridge University Press for supporting this colloquium.
I would like to begin by congratulating Arash Abizadeh. Hobbes and the Two Faces of Ethics is a splendid book. Even where I have disagreed with Abizadeh, the book has been a great help to me in framing central issues and in setting out pressing questions for different interpretations. I am sure that it will be a valuable resource for students of Hobbes for many years.
Here I will discuss Abizadeh’s views on the science of morality in Hobbes, and I will focus on his Chapter 3. I will begin from the principles that form the basis of that science and proceed to its conclusions, the laws of nature. In both cases, although I recognize the difficulties that Abizadeh has presented for what he calls subjectivism, I am also concerned about the alternative interpretation that he defends. On that interpretation, prudentialism, the view that one ought to desire and pursue one’s own good, is a foundational principle of moral science, which gives us reason to follow the laws of nature. The principle is distinct from any particular desire or knowledge, but its practical importance is guaranteed by epistemic access to the laws of nature: any sane adult can easily know the laws of nature.
Science, Hobbes writes in Leviathan, proceeds from definitions of words; to general affirmations; to syllogisms; to conclusions (L 7.4, cf. L 5.17). In the familiar case of the “science of virtue and vice” (L 15.40), Hobbes defines ‘right of nature’, ‘liberty’, and ‘law of nature’ (L 14.1–3); makes general affirmations in the right to everything and the fundamental law of nature (L 14.4); and proceeds by something recognizably like syllogistic reasoning to arrive at conclusions in the laws of nature (L 14–15).
Neither in Hobbes’s definition of ‘science’ nor in Leviathan 14–15 does the vexed term ‘principle’ arise, but I do not think that this is a significant problem for Abizadeh’s claim that the first normative principle is “desire and pursue your own good” (110). Hobbes does use ‘principle’ immediately before the L 5.17 definition of ‘science’ (see also the account of first philosophy at L 9). Moreover, where Hobbes does use the term ‘principle’ (or principium) more freely, as at De Corpore 15, he seems happy to have both definitions, such as the definition of ‘motion’, and also results of argument that are somehow fundamental, such as his version of the law of inertia, count as principles (DC 15.1).
I do think, however, that whatever Hobbes takes to be a principle he states explicitly and straightforwardly. Reason requires such transparency if it is to proceed on a solid footing. Where, then, Abizadeh claims that for Hobbes the first normative principle which grounds natural law is “desire and pursue your own good,” rather than the explicit definitions and fundamental precepts of Leviathan 14, I think his view is problematic. Considering the moral argument of Leviathan in parallel with the physical argument of De Corpore, it seems likely that Hobbes would have been happy to call his definitions, the right to everything, and fundamental law of nature “principles” in Leviathan. It seems quite unlikely, though, and contrary to his account of science, that he would have a fundamental principle that he does not mention.
Compare the case of Spinoza, whose psychology and method are similar in many respects to those of Hobbes. At the outset of his dictates of reason, Spinoza writes: “Because reason demands nothing contrary to nature, it therefore demands … absolutely, that each person should strive, as far as it is in him, to preserve his own being.” On the basis of this passage, one might argue that “desire and pursue the preservation of your being” is a principle of Spinoza’s dictates of reason. He starts with this emphatic statement about what we should do in general and other dictates of reason follow from it. Similarly, to take Abizadeh’s own comparison case (97), Thomas Aquinas explicitly and at the outset of his account of natural law makes it his first principle that the good is to be done and pursued and evil avoided (ST I–II q. 94 a. 2). If Abizadeh is right about Hobbes’s first principle, the case with Hobbes is quite different. He never does claim that one ought desire and pursue one’s own good. Notably, there is no such claim where one would expect to find it, at the beginning of Leviathan 14.
This point matters, I think, to Abizadeh’s assessment of interpretations of Hobbes that make him a subjectivist about reasons. If Hobbes were somewhere to assert as self-evident or to derive in argument the claim that one ought desire and pursue one’s own good, then the normativity of the laws of nature might well inherit their normativity from this principle: one ought to pursue peace because it is a necessary means to one’s good, and one ought to pursue necessary means to whatever ends one ought to pursue. The fact that Hobbes does not explicitly present this principle, though, is an impetus to take subjectivism and the deflationary sense of the normative that it presents seriously.
Turning now from the foundations to the conclusions of moral science, on Abizadeh’s view, we ought to understand Hobbes’s laws of nature as giving us reasons to act in particular ways that are independent of our particular desires or knowledge. Alternatively, if some subjectivist view is correct, then we ought to take them to give us reasons that are dependent upon our desires and knowledge. For example, on Watkins’s very simple “doctor’s orders” interpretation, I want to live, and I know that peace is means to survival (Watkins, 76–77). That knowledge gives me a motive (and so, in that sense, a reason) to seek peace. Textual evidence that may be relevant to the broader issue, then, is evidence concerning Hobbes’s views about whether human beings desire the ends secured by his laws of nature and whether human beings know that the laws of nature help to secure those ends. On the first topic, Abizadeh offers an excellent, nuanced account of Hobbes’s views about human desire. If subjectivism about reasons were to work, it would have to accommodate something close to desire as Abizadeh presents it. On the second topic, Hobbes’s views about human knowledge of laws of nature, however, I do have reservations about Abizadeh’s argument.
Abizadeh contends (122, 131) that, according to Hobbes, we need not know the laws of nature. If that were so, it would be a strong point against most varieties of subjectivist interpretation. The textual evidence that Abizadeh raises in support of this view, however, does not, to my eyes, do the job. One passage is Leviathan 30.4, where Hobbes writes that the grounds of sovereign rights need to be taught. Abizadeh paraphrases: “those who could know the laws of nature but do not, ‘need to be diligently, and truly taught’” (122). Perhaps one might work one’s way to the laws of nature from the rights of sovereigns, eventually, but the notions—and Hobbes makes this point emphatically (L 14.3)—are not simply intersubstitutable. Later, Abizadeh cites Leviathan 26.21, where Hobbes writes that the laws of nature need interpretation because we are frequently blinded by self-love and other strong passions. This also seems to me not directly related to the question of our knowledge of the laws of nature. The passage, I think, is naturally understood as one in which Hobbes notes that, although we all do know the laws of nature (perhaps because we all have a minimal degree of reason), we nevertheless easily misinterpret that law. The paragraph, after all, concerns the need for interpretation of all law. If knowing the law at all were a problem, that would be a more fundamental problem and would need to be addressed prior to the problem of misinterpretation.
A prominent passage in Leviathan states explicitly that all sane adults do know the laws of nature. At the conclusion of Hobbes’s moral science, Leviathan 15.40, he writes: “all men agree on this, that peace is good; and therefore also the way or means of peace … justice, gratitude … and the rest of the laws of nature.” Abizadeh’s contention that Hobbes defends a condition of epistemic access to natural law does offer a clear alternative reading of other passages (such as, L 15.35 and R&C 13) that a subjectivist might too quickly take to be equivalent to this passage: they do, read closely and without the context of 15.40, suggest that all can know the laws of nature and not that all do. In the light of 15.40, however, it seems to me that the subjectivist reading of these passages is better after all: all of us ought to know the laws of nature in the same sense that my socks ought to be in the drawer where I left them. In any case, the assertion that all minimally rational adults do know the laws of nature is perfectly consistent with the assertion that all minimally rational adults can know the laws of nature. Evidence that Hobbes maintains the latter, if that is what these other passages are, is not evidence that he does not hold the former.
Abizadeh’s analysis and criticism of subjectivist interpretations is excellent. In summary, I do worry that the alternatives he presents face pressing difficulties also. With respect to prudentialism, it is not what Hobbes would call “good and orderly” proceeding in science to have fundamental principles that are not explicit, and I do not think that Hobbes would have slipped this badly in his moral science. With respect to the view that we all must be able to know but need not know the laws of nature, it seems to me that Hobbes’s view is simpler: sane adults know the laws of nature. It is the enormously difficult function of the sovereign to create broader agreement and then fruitful cooperation from this small shared ground.
