Ignorance^4 by Ed Schenk

I would like to bring our attention to another very interesting piece (above) by the Dutch artist Ed Schenk. This one is titled “i to the fourth power” and it connotes an infinite loop of ignorance as well as asking a couple of questions. His question makes me think about asking more questions like the ones below. Can one answer be expressed as rational and the other irrational … can we express one type of ignorance being more rational and another type being more irrational?
Hmmmmm
