Landgrebe and Smith (2022) have recently offered an important mathematical argument against the possibility of Artificial General Intelligence (AGI): human intelligence is a complex system; complex systems have some properties that cannot be modelled mathematically; hence we have no viable way to build an AI that would be able to emulate human intelligence. The issue of complexity is thus at the heart of the Landgrebe and Smith approach, and they tackle this issue by postulating a set of conditions, derived from mathematics, for a system to be complex. I argue that Hayek’s “Theory of Complex Phenomena” offers an interesting alternative path to understanding what makes complex systems complex. This offers an argument complementary to that of Landgrebe and Smith, which approaches the issue of complexity from an ontological angle, and which is designed to show that AI systems are not the right kind of entity that may interact meaningfully with complex systems.

Our goal in this paper is to establish a set of criteria for understanding the meaning and sources of attributing (un)fairness to AI algorithms. To do so, we first establish that (un)fairness, like other normative notions, can be understood in a proper primary sense and in secondary senses derived by analogy. We argue that AI algorithms cannot be said to be (un)fair in the proper sense due to a set of criteria related to normativity and agency. However, we demonstrate how and why AI algorithms can be qualified as (un)fair by analogy and explore the sources of this (un)fairness and the associated problems of responsibility assignment. We conclude that more user-driven AI approaches could alleviate some of these difficulties.

Generally speaking, the present literature on agency has been heavily focused on human agency. This approach proves to be very useful for the immediate applications of the philosophy of agency, e.g. to develop a definition ready for use in ethics or political philosophy. However, there are some limitations to this line of thought, as, for instance, it poses too restrictive requirements on agency, like purposefulness, consciousness, or willingness. In this paper, I would like to tackle the question of agency with the need to include non-human agency in mind. I will set the foundations for a conceptual framework to define agency in the most general terms possible. This framework should be able to capture the conditions at which something possesses agency and the features of different kinds of agents in a way that includes animals and plants, mobs, institutions, ecosystems, AI machines, artifacts, and so on. In general, I claim that agency is based on a weak notion of intentionality, ‘directedness’, which does not require mentality or purposefulness.

_Posthuman Bliss? The Failed Promise of Transhumanism_ by Susan B. Levin presents a well-informed and structured critique to transhumanism. Not only transhumanist ethical and sociopo-litical applications are challenged: the theoretical assumptions and implications of transhumanism are made explicit and put into discussion, thereby confronting transhumanism as a worldview of its own, from metaphysics, to epistemology, to philosophy of mind, down to ethics and politics. This worldview is then constantly put to the test of Levin’s own Aristotelian essentialist framework, which sees the human being as a holistic whole and our role in the world as the complex process of attaining human flourishing. First, I will spend a few words to frame the general aim of the book and to delineate the main contents of the seven chapters. After that, I will deal critically with four interesting focal points, where further research may be prompted or the standpoint of the author may be challenged: the attribution of (rational) essentialism to transhumanism, the definition of well-being underlying transhumanist positions, the apparent tension between the sociopolitical im-plications of transhumanism and its cultivation of radical personal autonomy, the critical evaluation of Levin’s American-centered adaptation of her Aristotelian virtue-ethics approach.
