Socratic Irony and Neuroscience

Socratic Irony and Neuroscience


"The philosopher Socrates lived from 469 to 399 B.C. Although he is one of history’s most famous philosophers—arguably the most famous—he never wrote a word, unless we count a poem that he wrote in prison in Athens while awaiting execution. Why, you ask, was someone so important put to death? We know a great deal about the events leading up to his execution, mainly from an amazing document that survives, called the Apology. It was written by Plato and purports to be a recounting of what Socrates said in his defense at his trial. But, trial for what you ask, what was he charged with? The official charge was impiety, which to the Athenians at that time meant roughly that he was not a good citizen. That charge consisted of three counts: First, Socrates was charged with not worshipping the gods of Athens, second, he was charged with creating new gods, and third, he was charged with corrupting the youth. The last charge came about because many young men would follow Socrates around as he questioned the leading citizens of Athens, or anyone who claimed to have knowledge. The records of these interactions are part of what are known as the platonic dialogues, marvelous works of literature produced by his student Plato that depict what Socratic questioning was like. In them, Socrates shows via questioning that the person he is talking with who is claiming to have knowledge really doesn’t possess it, since he contradicts himself, or is simply unable to answer Socrates’ questions adequately..."

Excerpt from The Phantoms in the Brain

“…Consider next the simple act of smiling, something we all do every day in social situations. You see a good friend and you grin. But what happens when that friend aims a camera at your face and asks you to smile on command? Instead of a natural expression, you produce a hideous grimace. Paradoxically, an act that you perform effortlessly dozens of times each day becomes extraordinarily difficult to perform when someone simply asks you to do it. You might think it’s because if you walk over to any mirror and try smiling, I assure you that the same grimace will appear.

The reason these two kinds of smiles differ is that different brain regions handle them, and only one of them contains a specialized “smile circuit.” A spontaneous smile is produced by the basal ganglia, clusters of cells found between the brain’s higher cortex (where thinking and planning take place) and the evolutionary older thalamus. When you encounter a friendly face, the visual message from that face eventually reaches the brain’s emotional center or limbic system and is subsequently relayed to the basal ganglia, which orchestrate the sequences of facial muscle activity needed for producing a natural smile. When this circuit is activated, your smile is genuine. The entire cascade of events, once set in motion, happens in a fraction of a second without the thinking parts of your cortex ever being involved…”
