Krzysztof Gajos, "Design and Discrimination"

source: Harvard University   2016年8月31日
The currently prevalent one-size-fits-all approach to designing digital products inadvertently - but inevitably - leads to discrimination by making some people systematically a little more likely to succeed than others. In his lecture, Prof. Krzysztof Gajos will first show how current design practice discriminates against people based on their motor abilities, their ability to perceive color, or their subjective perception of what is aesthetically pleasing. He will then present a Computer Scientist’s approach to this problem: algorithms that automatically personalize design to provide more equitable access to digital resources.

Brains are conscious. The heart is not. What does the brain do that the heart does not do? How does it come to be that brains generate inner subjective experience, the movies of our minds? Why do brains seem to be the only place where such mental magic occurs?

The Block Universe B-Theory of Time - Eternalism (Huw Price)

source: Philosophical Overdose    2013年10月17日
The ancient philosophical dispute between Heraclitus and Parmenides in many ways continues to this day. One side accepts temporal Becoming as real and fundamental, while the other side declares it a subjective illusion. According to the former, dynamic view, time is conceived of as something which objectively "flows". This seems to require a distinguished present moment which is always changing, and which is ontologically special in some sense. But on the static conception of time (i.e. the block universe), there's no real objective passage. And so past, present, and future events are all ontologically equal. There's no privileged present moment or "now" built into the universe on this view. The universe is conceived as eternal and unchanging.
If something is missing from the 'block universe' conception of time, what is it, exactly? In this introductory survey Huw Price distinguishes three possible answers to this question, all apparently independent of each other. However, while there are three possible exits from the block universe, Price argues that they all seem to be dead ends.
This talk was part of a conference on whether we need a physics of temporal passage. It was given as part of the project New Agendas for the Study of Time: http://newagendasstudyoftime.wordpres...

Understanding Polytheism with P. Sufenas Virius Lupus

source: New Thinking Allowed       2016年9月5日
P. Sufenas Virius Lupus (his spiritual name) is a practicing polytheist and scholar. He is author of A Serpent Path Primer, Ephesia Grammata: Ancient History and Modern Practice, The Phillupic Hymns, The Syncretisms of Antinous, and other devotional books. Under his legal name of Phillip Bernhardt-House, he is author of Werewolves, Magical Hounds, and Dog-Headed Men in Celtic Literature. He is on the social science faculty at Skagit Valley College in Mount Vernon, Washington.
Here he notes that, in actual practice, polytheistic traditions are similar to those of the Catholic Church with its many devotional rites regarding saints. As certain humans are elevated to sainthood, so various polytheistic traditions have elevated other humans to the status of deities. Ancient Roman and Greek polytheism also included elements of satire – and even materialism. He, personally, maintains a clear distinction between the Jungian notion of archetypes that psychologists often associate with the pantheons of ancient religions and the living presence of willful, non-corporeal entities that are the foundation of polytheistic engagement.

New Thinking Allowed host, Jeffrey Mishlove, PhD, is author of The Roots of Consciousness, Psi Development Systems, and The PK Man. Between 1986 and 2002 he hosted and co-produced the original Thinking Allowed public television series. He is the recipient of the only doctoral diploma in "parapsychology" ever awarded by an accredited university (University of California, Berkeley, 1980). He is a past vice-president of the Association for Humanistic Psychology; and is the recipient of the Pathfinder Award from that Association for his contributions to the field of human consciousness exploration. He is also past-president of the non-profit Intuition Network, an organization dedicated to creating a world in which all people are encouraged to cultivate and apply their inner, intuitive abilities.
