The Mystery of Blindsight Helps Us Understand the Mind Better
How can a blind person demonstrate awareness of an object in his visual field — and yet not be conscious of it?Blindsight is the remarkable ability of some blind people to sense objects that they cannot actually see. It occurs when the blindness is caused by damage to the main part of the brain that processes visual information (the striate cortex). But the eyes themselves are intact. The eyes continue to see (sensation) but nothing is receiving the messages (perception). Or so we would think, except for this: One of the most contentious discussions in philosophy of mind and neuroscience is the nature of perception as opposed to sensation. How can we perceive objects in our environment? On a deeper level, what do we mean by “perception”? In what ways does perception differ from sensation, if at all? The neurobiology of Read More ›
A Reader Asks: Is It True That There Is No Self?
The assertion that self is an illusion is not even wrong — it’s self-refuting, like saying “I don’t exist” or “Misery is green”Sir, I am confused after reading the view of materialist philosophers regarding the sense of self. One of them, Thomas Meitzinger, a German philosopher and expert in conciousness, said that “There is no self” in his book. He said that self is an illusion produced by modules of brain. Is it so? Please help me understand this view. Thomas Meitzinger (pictured) is a prominent philosopher of mind who has a strong interest in artificial intelligence. I don’t know his work well, but what I do know of it, I find unintelligible. Perhaps it’s me, or perhaps he’s a sophist, or perhaps both. But this much is clear: My self cannot be an illusion, because having an illusion presupposes a self. Read More ›
How Much of Neuroscience Is an Unwitting Hoax?
Philosopher Ludwig Wittgenstein saw that much materialist neuroscience was neither true, nor false, just nonsenseIn 1996, NYU physics professor Alan Sokal published an article in a journal of postmodern cultural studies. The article, “Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity,” was a hoax. Sokal simply assembled more or less meaningless phrases about cultural theory and quantum physics in a grammatically correct but meaningless manuscript. He revealed the hoax a few weeks later in a magazine. The hoax ignited a storm of controversy and, in the view of many, revealed the essential sham at the core of postmodern philosophy. What Sokal (pictured) was doing, whether he knew it or not, was invoking philosopher Ludwig Wittgenstein’s salient critique of philosophy and science, which is that much of our discourse is language games.
