the same way I have followed up to this point’ (4p18s, emphasis added). This is a reason to
think that Spinoza takes himself to be working within the tradition that holds that egoism
is prima facie at odds with the essence of morality. As a result, it is important to get a clear
understanding of the strategy that Spinoza follows to show that psychological egoism and
ethical egoism are compatible with a non-mercenary, benevolent concern for others.
Nadler’s investigation clarifies the nature of the link that, for Spinoza, binds the ego-
istic self to the well-being of others. According to Nadler, even though Spinoza’s the-
ory of virtue is, formally speaking, egoistic in the sense that virtuous action is action
according to one’s nature, it is not, he argues, narrowly egoistic. The nature that we
ethically ought to live according to—reason—is one that we share with others, and we
share it with others, not in the sense that we share a limited, spatially located resource
like clean water but, rather, in the sense that we share an unlimited, empowering, and
identity-forming resource like language. On Nadler’s reading, given that knowledge is
our nature and, equally important, given the nature of knowledge, there is no meaning-
ful difference between a concern for one’s own true advantage and a non-mercenary,
benevolent concern for the real well-being of others.
In his essay, ‘Spinozistic Constructivism’, Charles Jarrett examines a third reason for
thinking that Spinoza aims to debunk morality: his apparent denial of what we will
call moral realism. Before turning to Jarrett’s essay, it may be helpful to say something
about the interpretative difficulties arising from Spinoza’s various claims pertaining to
this subject. The central question is how to interpret Spinoza’s denial that the proper-
ties of perfection and goodness are real. He writes that perfection and imperfection
‘are only modes of thinking, i.e., notions which we are accustomed to feign because we
compare individuals of the same species or genus’ and that as far as ‘good and evil are
concerned, they also indicate nothing positive in things, considered in themselves, nor
are they anything other than modes of thinking, or notions we form because we com-
pare things to one another’ (4pref).

Some scholars read these claims as expressing the anti-realist view that perfection
and goodness are not real properties in the sense that they do not exist independently
of anyone’s desires, emotions, and beliefs.

This reading is supported, first, by Spinoza’s

Spinoza’s denial that good and bad are real properties in some sense of the term ‘real’ is also quite explicit
in the earlier Short Treatise on God, Man, and His Well-Being: ‘All things which exist in Nature are either
things or actions. Now good and evil are neither things nor actions. Therefore, good and evil do not exist in
Nature’ (KV I, 10, C 93).
