"labyrinth of knowledge"
I think a possible interpretation of this image could do with divergent evolution. In order for the human organism to survive we have to accomplish a certain set of task or goals in our enviornment to eat/live and reproduce.
Humans through a complex series of unlikely events involving a thumb, have created an incredibly complex society in which you have to understand how to file your own taxs, and drive a car in order to survive. You must spend most of your time collecting knowledge on a vast array of subjects to 'understand' them, instead I think, of experiencing them. In this image you can see humans walking through a Maze of knowledge, a privilege and a giant burden. The fish have evolved down a different path of extremes that focus on being present in moment for survival (protection of self and foraging for food)
When I look at this image I personally want to be one of these fish, but that's just my take.
