Psychedelic drugs such as psilocybin, LSD and DMT are known to induce powerful alterations in phenomenology. Perhaps of most philosophical and scientific interest is their capacity to disrupt and even “dissolve” one of the most primary features of normal experience: that of being a self. Such “peak” or “mystical” experiences are of increasing interest for their potentially transformative therapeutic value. While empirical research is underway, a theoretical conception of the mechanisms underpinning these experiences remains elusive. In the following paper, psychedelic-induced (...) ego-dissolution is accounted for within an active inference framework, as a collapse in the “temporal thickness” of an agent’s deep temporal model, as a result of lowered precision on high-level priors. The argument here is composed of three moves: first, a view of the self-model is proposed as arising within a temporally deep generative model of an embodied organism navigating an affordance landscape in the service of allostasis. Next, a view of the action of psychedelics as lowering the precision of high-level priors within the generative model is unpacked in terms of a high Bayesian learning rate. Finally, the relaxation of high-level priors is argued to cause a “collapse” in the temporal thickness of the generative model, resulting in a collapse in the self-model and a loss of the ordinary sense of being a self. This account has implications for our understanding of ordinary self-consciousness and disruptions in self-consciousness present in psychosis, autism, depression, and dissociative disorders. The philosophical, theoretical and therapeutic implications of this account are touched upon. (shrink)

This paper deals with the recently published work by Hannah Arendt, "Some Questions of Moral Philosophy", which is her most extensive discussion of moral issues. What emerges from this work is a fuller account of what genuine morality is. Writings that she published had prepared her readers for the idea that genuine morality is Socratic morality, which holds that it is better for the person to suffer wrong than to do wrong. That means, in the contexts of resistance to totalitarianism (...) and to tyranny and despotism, that it is better to suffer wrong than to be an accomplice or passive bystander of wrong done to others when one could be safe if one did not resist. On the other hand, Arendt makes it clear that spurious morality in the form of what she calls "the morality of mores" makes people accomplices or passive bystanders. For them, morality is merely conformity to the prevailing norms, and their conformity is underlain by self-love. Thus, morality in one conventional sense sustains political evil, while morality in the real sense impels the individual's effort to resist evil. But this paper also tries to indicate that for Arendt the evil of totalitarianism is not simply the infliction of atrocious suffering and premature death on millions of people. Rather, the worst part of the evil is that atrocious suffering dehumanizes its victims. The loss of humanity is an existential loss: a deprivation of the human status. Correspondingly, the most noteworthy aspect of resistance to evil is to give testimony to the human stature: the unique human capacity to engage in free audacious activity. Status and stature constitute human dignity; and for Arendt human dignity is essentially existential in importance and only secondarily moral. (shrink)

So far as his critical employment of the concept is concerned, the thing in itself is not a second object. The thing in itself is given in its appearances; it is the object which appears. In other words, the object is taken in a twofold sense. There is no contradiction, Kant maintained, in supposing that one and the same will is, as an appearance, determined by the laws of nature and yet, as a thing in itself, is free. He never (...) meant to hold that the self of the theoretical reason and the self of the practical reason are two separate and distinct entities. It is one and the same object considered from two perspectives. In this sense the thing in itself is purely a limiting concept. So far as the critical method is concerned, objects are always considered from a particular and limited perspective, e.g. science, morality, art, et cetera. This is the central meaning of his theory of appearances. In this employment of the concept it is completely meaningless to speak of the thing in itself as a cause of appearances. The critical distinction between appearances and things in themselves is not intended to be a distinction between subjective sense data and public objects, but between public objects as given according to two or more modes. This involves no extension of the category of causality beyond appearances. Moreover, it is not open to the charge that an unknown object is given the attribute of existence. The thing in itself is known as an appearance. By definition that is the only way that it could be known. To say that we know only appearances and not things in themselves is to state an obvious tautology, namely that objects are known only as they are known. (shrink)

Basic yet familiar and non-technical features of time are investigated. Two novel and detailed arguments are advanced defending the common view that 'time rolls relentlessly'. A number of hitherto neglected but important differences between spatio-temporal location and every other physical property are discussed. Also explored are the locations of circular time; the uniformity of nature, temporal positions and possible worlds, as well as the famous, unresolved problem, 'Why do we know so much more about the past than about the future?'. (...) For those who wish to delve deeper, a portion of the book consists of problems to ponder and their possible solutions. (shrink)

Me, You, Us addresses a range of issues in moral and political philosophy and moral psychology, but are unified by their starkly individualistic view of the moral subject. They challenge recent tendencies to conceptualize normative issues in terms of relationships, collectivities, and social meanings.

This book provides an in-depth analysis of Thomas Hobbes's philosophy and political writings. The author argues that Hobbes was not only a philosopher, but also a publicist who played an important role in shaping political discourse in his time. This is an essential resource for anyone interested in political philosophy and the history of ideas. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Science is at a cross-roads. For several decades, the Standard Model of particle physics has managed to fit vast amounts of particle scattering data remarkably well, but many questions remain. During those decades, some sophisticated theoretical hypotheses such as string theory, quantum gravity, and quantum cosmology have been proposed and studied intensively, in an effort to break the log-jam of the Standard Model. None of those hypotheses have succeeded to date. Of greater concern is the increasing tendency by some practitioners (...) in those fields to downplay the empirical principles of science. In response, this book is a restatement of those principles, covering numerous aspects of observation. A particular focus is on contextuality versus realism, the two fundamentally contrasting ideologies that underpin modern physics. (shrink)
