Beatrice de Gelder’s article “Uncanny Sight for the Blind” raises fascinating evolutionary questions about consciousness. Given that sight slowly evolved from the first light-sensing structures to today’s sophisticated ability to perceive, focus on and be aware of the world around us, when did conscious awareness get paired with sight? Presumably a plant that turns toward the sun has no awareness of doing so. What about insects, reptiles or fish? Is a trout aware that the dark disturbance on the water’s surface is a bug that it can eat, or is its swift rising to consume the insect simply a nonaware response to a perception that is more akin to “blindsight” than it is to our awareness? Perhaps this line of research will help us to know which species have consciousness that is akin to human awareness.
Steve Mirsky’s “140-Character Study” [Anti Gravity] is humorous and enjoyable, but the illustration’s attempt to render the word “Tweet” as a Greek inscription on a statue is an abject failure. Any classicist worth their bow tie and suede jacket would tell you that the only way to render the /w/ sound in ancient Greek is through the oft-overlooked digamma, uppercase , lowercase . Your artist used an omega, which many Greek fonts link with the W on our keyboard but which was nothing more than a long O-sound.
