"The realization that our mental functioning is largely irrational was arrived at by several thinkers at the same time, including Friedrich Nietzsche... Freud, who was much influenced by both Darwin and Nietzsche... was its most profound and articulate exponent. ...Schnitzler, Klimt, Kokoschka, and Schiele also discovered and explored new aspects of our unconscious mental life. They understood women better than Freud... and they saw more clearly than Freud the importance of an infant's bonding to its mother. They even realized the significance of the aggressive instinct earlier than Freud did. ...Plato discussed unconscious knowledge ...pointing out that much of our knowledge is inherent in the psyche in latent form. ...Hermann von Helmholtz... advanced the idea that the unconscious plays a critical role in human visual perception."

“Mountcastle discovered that tactile sensation is made up of several distinct modalities; for example, touch includes... hard pressure on the skin as well as a light brush... He found that each distinct submodality has its own private pathway within the brain and that this segregation is maintained at each relay...”

“As the art historian Emily Braun has documented, Klimt read Darwin and became fascinated with the structure of the cell... Thus, the small iconographic images on Adelle's dress are not simply decorative... they are symbols of male and female cells: rectangular sperm and ovoid eggs. ...designed to match the sitter's seductive face and her full-blown reproductive capacities.”

“Science may explain aspects of art but it will not replace the inspiration that art evokes...”

“Unlike vision, touch, or smell, which are prewired and based on Kantian a priori knowledge, the spatial map presents us with a new type of representation, one based on a combination of a priori knowledge and learning. The general capability for forming spatial maps is built into the mind, but the particular map is not. Unlike neurons in a sensory system, place cells are not switched on by sensory stimulation. Their collective activity represents the location where the animal thinks it is.”

“As astronomy and physics inspired the Enlightenment, so biology inspired Modernism. ...This new view led to a reexamination in art of the biological nature of human existence, as evident in Édouard Manet's Déjeuner sur l’Herbe... Manet's painting... reveals a theme... the complex relationship between the sexes and between fantasy and reality. ...also startlingly modern because of its style. Several decades before Cézanne began to collapse three dimension into two, Manet here had already flattened the viewer's sense of perspective...”

“The function of the modern artist was not to convey beauty, but to convey new truths.”
