Berkeleyan idealism, or ‘immaterialism,’ has had an enormous impact on the history of philosophy during the last three centuries. In recent years, Christian scholars have been especially active in exploring ways that Berkeley's thesis may be fruitfully applied to a variety of issues in philosophy and theology. This essay provides an overview of some of the ways Christian philosophers have deployed immaterialism to solve problems and generate insights in metaphysics, philosophy of mind, philosophy of science, philosophy of religion, and philosophical (...) theology.

According to a traditional view, perceptual experiences are composites of distinct sensory and cognitive components. This dual-component theory has many benefits; in particular, it purports to offer a way forward in the debate over what kinds of properties perceptual experiences represent. On this kind of view, the issue reduces to the questions of what the sensory and cognitive components respectively represent. Here, I focus on the former topic. I propose a theory of the contents of the sensory aspects of perceptual (...) experience that provides clear criteria for identifying what kinds of properties they represent. (shrink)

The promise of virtual reality is that it may eventually lead us to a "third state of consciousness" transcending the objective reality of our embodied beings and opening up to us a world of expanded realization. However, the recurring themes of our hero myths, both religious and secular, remind us of the importance of remaining grounded in the real world of embodied people and phenomenal perception. Advances in neuroscience even suggest that unconscious processing of perceptual stimuli may guide our behaviors. (...) Thus, the journey from the phenomenal to the noumenal is a round-trip ticket. We take with us the strength of our moral convictions to serve us on our journey and bring back the spiritual expansion that always comes of travel. (shrink)

The concept of ecosystem health is problematic. Do ecosystems as such exist? Is health an objective condition of organisms or is it socially constructed? Can 'health' be unequivocally predicated of ecosystems? Is ecosystem health both objective and valuative? Are ecosystem health and biological integrity identical? How do these concepts interface with the concept of biodiversity? Ecosystems exist, although they are turning out to be nested sets of linked process-functions with temporal boundaries, not tangible superorganisms with spatial boundaries. Ecosystem health – (...) or normal occurrence of ecological processes and functions – is an objective condition of ecosystems, although the concept of ecosystem health allows some room for personal and social determination or construction. Ecosystem health is prudentially, aesthetically, and intrinsically valuable, although the value of ecosystem health is subjectively conferred. Biodiversity and biological integrity are different from, but not unrelated to, ecosystem health. Together these three normative concepts represent complementary conservation goals. (shrink)

The majority of the world’s cultures encourage or require members to enter alternative states of consciousness while involved in religious rituals. The question is, why? This paper suggests an explanation for the culturally prescribed ASC from the view of Fisher information. It argues from the position, first put forward by Emile Durkheim in his magnum opus, The Elementary Forms of the Religious Life, that all religions are grounded in reality. It suggests that many of the structural elements of cultural cosmologies (...) are similar and that the ritual induction of ASC may help to bring individual experience into greater accord with a pan-human eidetic cosmology, and thus with certain invariant attributes of reality. The necessity of this process is demonstrated by recourse to Fisher information. The paper shows how experiences generated during alternative states of consciousness may help to maintain a minimal level of realism in the interests of adaptation to what is in other respects a transcendental reality.

The primary purpose of the paper is to try to prove that it is impossible to write or understand history without making epistemological and ontological assumptions, In particular assumptions about whether physical objects and processes are within or beyond the limits of what can be made empirical or conscious.

Ludwig Wittgenstein suggests that ?A serious and good philosophical work could be written consisting entirely of jokes?. The idea for this dialogue comes from a conversation that Michael Peters and Morwenna Griffiths had at the Philosophy of Education of Great Britain annual meeting at the University of Oxford, 2011. It was sparked by an account of an assessment of a piece of work where one of the external examiners unexpectedly exclaimed ?I knew Jean-Paul Sartre?, trying to trump the discussion. This (...) conversation is a dialogue about comedy and humor as a basis for philosophy, education and pedagogy that provides an introduction to recent works and a context for ongoing research. The concluding section provides further reflection on some of the main themes, drawing attention to the significance of humor in dialogues within philosophy and education, and suggesting that it has a particular role in resisting managerialism at all levels of educational institutions.
