Abstract Several questions regarding Spinoza's concept of essence have been the topic of recent scholarly debate. In this paper, I show that the connection between love, desire and essence is ubiquitous in the Ethics, as well as metaphysically and psychologically coherent; moreover, it provides the key to answer unresolved questions. Analyzing the notion of essence through Spinoza's theory of love shows that essence can be expressed in different ways, and be reflected through different objects of love. These objects of love, in turn, signify the extent to which the affected mind understands itself, God and things in the world. Each object is a different expression of the same single, unique essence of the individual, and therefore of the desire which defines them. This interpretation allows to solve some puzzles about essence, and also to establish the importance of love in Spinoza's philosophy as a whole-especially his epistemology and ethics.

Abstract In this paper we present an analysis of the role of randomized controlled trials (RCTs) in the regulation of health claims (claims about additional health benefits provided by foods). Currently there is a line of thought in the nutrition sciences and in regulation that data from RCTs may be able to minimize, or even make superfluous, the role played by expert knowledge in decision making. We analyze the limitations of, as well as the possible intervention of expert judgment in RCTs in pharmacology and nutrition. As a result of our analysis, we argue that both RCTs and expert knowledge are necessary for data generation in health claim regulation. We argue that as far as data generation is concerned, nutrition is more complex than pharmacology, implying that RCTs are more difficult to effectively design and execute. What the latter means is that in nutrition and health claim regulation, expert knowledge is even more important than in pharmacology.

Abstract In his logical foundation of arithmetic, Frege faced the problem that the semantic interpretation of his system does not determine the reference of the abstract terms completely. The contextual definition of number, for instance, does not decide whether the number 5 is identical to Julius Caesar. In a late writing, Quine claimed that the indeterminacy of reference established by Frege’s Caesar problem is a special case of the indeterminacy established by his proxy-function argument. The present paper aims to show that Frege’s Caesar problem does not really support the conclusions that Quine draws from the proxy-function argument. On the contrary, it reveals that Quine’s argument is a non sequitur: it does not establish that there are alternative interpretations of our terms that are equally correct, but only that these terms are ambiguous. The latter kind of referential indeterminacy implies that almost all sentences of our overall theory of the world are either false or neither true nor false, because they contain definite descriptions whose uniqueness presupposition is not fulfilled. The proxy-function argument must therefore be regarded as a reductio ad absurdum of Quine’s behaviorist premise that the reference of terms is determined only by our linguistic behavior.

Abstract Despite the fact that the discussion on the economic man flourishes in John Stuart Mill’s work, this does not mean that this issue has not been previously discussed, at least, not in clear terms. The aim of this article is to demonstrate that even if Adam Smith never specifically characterized the person who deals with economic affairs, he pointed out some of his characteristics in his writings. We can find some clues to his thoughts on that issue in Theory of Moral Sentiments (1759), Lectures on Jurisprudence (1762) and The Wealth of Nations (1776). In this article, Smith’s homo oeconomicus is approached in three aspects: rational, moral and emotional. In addition, we also argue that the philosopher had advanced some studies of psychology and behavioral economics that would be developed from the twentieth century, which is discussed when we approach the emotional side of Smith’s economic man.

Abstract In this review I provide a brief analysis of the main features of the collective volume Shifting Concepts (Oxford University Press, 2020), edited by Teresa Marques and Åsa Wikforss. The volume addresses several related topics, and it contains contributions from psychologists and philosophers. It deals with the topic of concept variation understood in a broad sense, for it tackles diachronic, contextual, interpersonal and even intrapersonal variation; besides, the second part of the book is devoted to the topic of concept revision and amelioration. I provide a brief description of the book and then I critically assess each of the contributions.
