I like to define it as seeing something in the Same Light or Context—so to speak, like a theme, genre, or overall look and feel to a series or whole. Similar to how IKEA is supposedly Swiss inspired home furniture and cannot deviate from that path to be Mongolian Inspired.
Google has defined Esthetics as “A set of principles underlying and guiding the work of a particular artist or artistic movement.”, but that sounds very specific to just manmade design. To me, design is everything from the soil to the sun. Therefore esthetics should be just as broad. Then again, there may be a better word I’m not thinking of other than Esthetics. Perhaps it hasn’t been invented yet? Or maybe I need to start drinking because this hurts my head.
