Theoretically, the ‘Love Hormone Measurement System’ has some utility. We form bonds to others with every kind word and familiar touch, it may be useful for many different populations of people to gain a clear sense of how they really feel about “loved ones”, and why that is.
Also a general purpose sense of whether a person has spent too long or too little in the sunlight might be very harm reducing. A lack of light can cause myopia, too much is cancerous...
For myself...maybe a sense of polyrhythms?
“They are ways of passing off ignorance as truth” Wrong, the author used the example of Shakespeare being true. That is not ignorance, that is understanding the importance of a priceless work of art. Not just it’s nature as an artifact of history of drama/literature/psychology/etc, but the stories and poetry themselves are “true” in pretty much every sense that matters. Maybe there wasn’t really a Romeo and Juliet tween blood sacrifice that helped solidify the postfeudalistic sociopolitical strucuture in Verona, but that play is still an excellent portrayal of that time and place.
