I argue that a study of the Nicomachean Ethics and of the Parva Naturalia shows that Aristotle had a notion of attention. This notion captures the common aspects of apparently different phenomena like perceiving something vividly, being distracted by a loud sound or by a musical piece, focusing on a geometrical problem. For Aristotle, these phenomena involve a specific selectivity that is the outcome of the competition between different cognitive stimuli. This selectivity is attention. I argue that Aristotle studied the (...) common aspects of the physiological processes at the basis of attention and its connection with pleasure. His notion can explain perceptual attention and intellectual attention as voluntary or involuntary phenomena. In addition, it sheds light on how attention and enjoyment can enhance our cognitive activities. (shrink)

Aristotle is a political scientist and a student of biology. Political science, in his view, is concerned with the human good and thus it includes the study of ethics. He approaches many subjects from the perspective of both political science and biology: the virtues, the function of humans, and the political nature of humans. In light of the overlap between the two disciplines, I look at whether or not Aristotle’s views in biology influence or explain some of his theses in (...) political science. I show that we should not seek a unified answer to this question, for the relationship between the two disciplines varies depending on the topic. In some cases, e.g. the nature of the human function, the biological background is likely to be endorsed as one of the presuppositions of the ethical enquiry. In other cases, e.g. the study of social hierarchies, even though the ethical works and the biological works come to similar conclusions, it is hard to establish that the biological approach is intended to provide support to the ethico-political approach. In conclusion, I show that Aristotle’s political science and his biology are in conflict at least in two important cases: his account of justice towards non-human animals and his exhortation to contemplate.

Aristotle’s works on natural science show that he was aware of the affective powers of colour. At De an. 421a13, for example, he writes that hard-eyed animals can only discriminate between frightening and non-frightening colours. In the Nicomachean Ethics, furthermore, colours are the source of pleasures and delight. These pleasures, unlike the pleasures of touch and taste, neither corrupt us nor make us wiser. Aristotle’s views on the affective powers of colours raise a question about the limits he seems to (...) place on the affective powers of pictures at De an. 427b15-24, where he implies that pictures do not affect us immediately. In this paper, I examine the contrast between the affective powers of colour and the affective powers of pictures. I argue that colours can give rise to pleasure and pain in themselves and generate emotions incidentally. Similarly, pictures can please us or affect us in themselves and incidentally. In light of this account, I suggest that, on a plausible reading of De an. 427b15-24, the affective powers of pictures as mimetic objects are not immediate because they require an intervening cause in order to be effective. The representations of pictures and statues affect us either with the mediation of deception or with the mediation of interpretation. (shrink)

I argue that, for Aristotle, virtues of character like bravery and generosity are, like the emotions, properties that require a hylomorphic analysis. In order to understand what the virtues are and how they come about, one needs to take into account their formal components and their material components. The formal component of a virtue of character is a psychic disposition, its material component is the appropriate state and composition of the blood. I defend this thesis against two potential objections and (...) I show that it is relevant for a study of Aristotle’s ethics. (shrink)
