Space and Gravity: We understand intangible values like price or worth using spatial and physical metaphors: high or low, rising or falling. Although intangible value has no physical properties, we mentally map it onto ideas of space and gravity. For instance, we imagine a lowest point for value, equating a price drop with a sharp fall and a rise with a slow climb, as if gravity is at work. This illustrates that our thinking applies the rules of space and gravity to even the most abstract concepts. - Joseph’s “just my thoughts”
The essence of cubism is to get rid of the viewpoints of the object. Cubism shows us the inside and outside, top and bottom, front and back of the object simultaneously with 2D reorientation, as a result, the observer's viewpoints disappear altogether. Finally, cubism makes us see the whole of the object. If you want to see the real world, throw away your viewpoints completely. - Joseph's "just my thoughts"
