Body Mind Material Current consensus in neuroscience: reductive monism Methodological reductionism Versus Ontological reductionism

Cross-over trial of 36 volunteers psilocybin (30 mg/70 kg) (mushrooms 5HT2a,cR) methylphenidate hydrochloride (40 mg/70 kg) All volunteers had some knowledge of religious activities…. Half on a daily basis Assessed by 32-item questionnaire “Mysticism Scale” Magic mushrooms and God Griffiths Psychopharmacology (2006) 187:268–283 Drug 1 Drug 2 Test 1Test 2

“You are all healthy people, ….but you have no idea what joy that joy is which we epileptics experience the second before a seizure... I do not know whether this joy lasts for seconds or hours or months, but believe me, I would not exchange it for all the delights of this world.” Dostoyevsky 1821-1881 Mystical seizures
“All of our behaviour can be traced to biological events about which we have no conscious knowledge.” - Sam Harris “We feel we choose, but we don’t,” says Patrick Haggard, a neuroscientist at University College London. “You may have thought you decided whether to have tea or coffee this morning, for example, but the decision may have been made long before you were aware of it.” Our brains are in control not us

NMDA receptor hippocampus behaviour Long-term potentiation Spatial navigation Top-down processing as well as bottom-up

Collision of bottom up and top-down: the human predicament “I do not understand my own actions. For I do not do what I want, but I do the very thing I hate. ….. I can will what is right, but I cannot do it. For I do not do the good I want, but the evil I do not want is what I do. Now if I do what I do not want, it is no longer I that do it, but sin that dwells within me. So I find it to be a law that when I want to do what is good, evil lies close at hand. For I delight in the law of God in my inmost self, but I see in my members another law at war with the law of my mind, making me captive to the law of sin that dwells in my members. Wretched man that I am! Who will rescue me from this body of death?” Romans 7
Body Soul / Mind God Material Immaterial My current position: non-reductionist physicalism The importance of emergence
God in the Synapse in the Vatican garden John Eccles and Karl Popper The Self and its Brain 1984
Old Testament (nepes) “Life” itself, as in Gen 2:7 “man became a living soul [being]” No suggestion of immaterial separate soul Little suggestion of afterlife New Testament (psyche) At the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed. For this perishable body must put on imperishability, and this mortal body must put on immortality. When this perishable body puts on imperishability, and this mortal body puts on immortality, then the saying that is written will be fulfilled: "Death has been swallowed up in victory." (1Co 15:51-54) Jesus replied, "Truly I tell you, today you will be with me in Paradise." (Luk 23:43) Biblical position on soul
Life after death may be as an immaterial soul before the new body resurrected for a dualist requires a resurrected body for a physicalist. So where is the continuity? Views of the body A dualist may despise the flesh A physicalist must respect the body Pastoral consequences
Many Christians are implicit dualists This is problematic for neuroscientists Monist accounts of brain tend to be reductionist and exclude God A non reductive physicalist leaves space for God Most behaviour is immediately determined by our biology Our behaviour may alter brain structure There is a dynamic interaction between brain and mind Summary

Karen Armstrong Aged 17, entered Catholic convent. 7 years later: left. Tried to teach. “Fainting episodes”. Went to “hell”. Seven years later: diagnosed with epilepsy Author of Through the narrow gate The spiral staircase History of God
Karen Armstrong “Certainly just before I have a grand mal fit I have a 'vision' of such peace, joy and significance that I can only call it God………. What I can say, however, is that if my 'visions' have sometimes let me into 'Hell' they have also given me possible intimations of a Heaven which I would not have been without.”
