Abstract The defining characteristic of this group of drugs is their ability to induce profound changes in sensory perception, patterns of thinking, and emotion without at the same time clouding the mind. Terminology is difficult, because it always seems to be judgement-laden; one person’s psychotomimetic (psychosis mimicker) is another’s psycholytic (literally mind loosener, and by...
Since Descartes' dualism, with his res extensa and res cogitans, six fundamental problems in the philosophy and natural history of mind are these: 1. how does mind act on matter? 2. If mind does not act on matter is mind a mere epiphenomenon? 3. What might be the source of free will? 4. What might be the source of a responsible free will? 5. Why might it have been selectively advantageous to...
The ability to rise above the present environment and reflect upon the past, the future, and the minds of others is a fundamentally defining human feature. It has been proposed that these three self-referential processes involve a highly interconnected core set of brain structures known as the default mode network (DMN). The DMN appears to be active when individuals are engaged in...
Authentic Movement facilitates a descent into the inner world of the psyche through natural movement. Through the process we are reconnected with deeper instinctual resources and spiritual intelligence that dwell in the molecular structure of the cells, and recover unlived parts of our nature on intrapersonal, interpersonal and transpersonal levels. The practice develops a sense of embodied...
Practicing meditation while focusing on a sound or a symbol influenced midlatency auditory evoked potentials (MLAEPs). Cyclic meditation (CM) is a technique combining yoga postures with meditation while supine, which has influenced the P300 event-related potential. The effects of CM on MLAEPs have not been previously studied. The MLAEPs were studied before and after the practice of CM compared...
This is a study of one of the levels, or hypostases, in the Neoplatonist Plotinus’ metaphysical hierarchy, the Intellect (Nous). Yet, a reader coming to it with the expectation of finding an inclusive study of this part of his metaphysics might well be slightly disappointed. This is because the book’s actual topic is ideally perfect thinking. For Plotinus, just as for Aristotle, metaphysics is...
This paper gives continuity to the criticism, undertaken in two papers previously published in this journal, of transpersonal systems that fail to discriminate between nirvanic, samsaric, and neithernirvanic- nor-samsaric transpersonal states, and which present the absolute sanity of Awakening as a dualistic, conceptually-tainted condition. It also gives continuity to the denunciation of the...
Regular use of illegal drugs is suspected to cause cognitive impairments. Two substances have received heightened attention: 3,4-methylenedioxymethamphetamine (MDMA or 'ecstasy') and delta-9-tetrahydrocannabinol (THC or 'cannabis'). Preclinical evidence, as well as human studies examining regular ecstasy consumers, indicated that ecstasy use may have negative effects on learning, verbal memory...
Abstract This article offers an overview of the structure and significance of Merleau‐Ponty's phenomenology. Neither a psychological nor an epistemological theory, Merleau‐Ponty's Phenomenology of Perception is instead an attempt to describe perceptual experience as we experience it. Although he was influenced heavily by Husserl, Heidegger, and Gestalt psychology, his work departs significantly...
Central to kabbalistic behavior is the conduct of the mind, as reflected in the marked emphasis of the texts of medieval Kabbalah on concrete instruction and prescription. Because Isaac ben Samuel of Akko was indebted to the meditative posture of eastern Kabbalah, this characterization is highly applicable to his two works, Me'irat 'Einayim and 'Ozar Hayyim. Isaac's attempt to instruct his...
