Challenges from mathematicians and biologists

• There is no such thing as homogeneous space
• Henri Poincaré and Ernst Machthe physiological
  foundation for the natural development of
  geometrical space (133)
• Elie de Cyon Only the semicircular canals are
  inherent, and our sense of space derives from
  them and remains dependent upon them. (136)

Umwelt vs. Umgebung

• Baron Jakob von Uexküll (137)
• Too often, he affirms, we imagine that the
  relations a certain animal subject has to the
  things in its environment take place in the same
  space and in the same time as those which bind us
  to the objects in our human world. This illusion
  rests on the belief in a single world in which
  all living beings are situated

Umwelt vs. Umgebung

• Uexküll shows that such a unitary world does
  not exist, just as space and a time that are
  equal for all living things do not exists. The
  fly, the dragonfly, and the bee that we observe
  fling next to us on a sunny day do not move in
  the same world as the one in which we observe
  them, nor do they share with usor with each
  otherthe same time and the same space.

Cézannes break with the rule of perspective

• Cézanne was the first to introduce a truly
  heterogeneous space in a single canvas with
  multiple perspectives of the same subject. (141)
• composition of forms on the flat surface of the
  canvas(141)
• conventions for accurately rendering volume and
  depth were secondary(141)
