- You should look at certain walls strained with damp, or at stones of uneven colour. If you have to invent some backgrounds you will be able to see in these the likeness of divine landscapes, adorned with mountains, ruins, rocks, woods, great plains, hills and valleys in great variety; and expressions of faces and clothes and an infinity of things which you will be able to reduce to their complete and proper forms. In such walls the same thing happens as in the sound of bells, in whose stroke you may find every named word which you can imagine (61).
While possibly good advice, it tells us more about the extent of Leonardo’s own active imagination and his ability to convert environmental sights and sounds into a new vision or voice, transformed from a stain on a wall or heard in clanging bells. Leonardo’s advice notwithstanding, this is not a universal skill. Rather, it is more likely encountered in altered states of consciousness, from whatever the source—sleep deprivation, isolation, drug usage, or organic injury to the brain, such as epilepsy or head trauma. A left-hander’s bilaterally organized brain, with an enhanced right hemisphere, could make associative visual or auditory connections that typical minds could not.
- Although each hemisphere has its own preferences and approaches, each contributes to make a whole person only when the corpus callosum integrates the two. But in the process of generating a major creative insight, a disconnect must occur between the two halves. Arthur Koestler called this the ‘hemispheric bisociation’ (91-92) . . . [Koestler also described the act of creation as “thinking aside” and it was clear to him that there could be no truth without beauty, whether artistic, mathematical, or scientific. If you look closely at the tattered cover of my 1989 edition of Koestler's classic, you'll see that the figure is tossing about pages of Leonardo's drawings, a poem, and musical notes. [These were the days when cover art was beautifully enigmatic, not diagrammatic or technological.]
Still describing the typical mind, Shlain says the “the right brain is essentially bereft of language, the description in words of how the creative process proceeds is practically impossible. Ask artists or scientists how they arrived at their most novel and creative work, and you will no doubt receive either an inarticulate answer or the left brain’s confabulation (98-9).” He does not postulate that language can be dominant on the right or spread out in both hemispheres.
- Creativity is at its base a combination of fear and lust. Danger and sex are the fundamental processes that artists traditionally call upon to create a work of art. Of course, he or she is not aware that these are the root causes. Creativity begins with perceiving a pattern, a feature, or an alternative use for a common object. After recognizing something novel, the artist breaks down the observation into its component parts. This is primarily a left-brained function, reductionist and analytic. An artist will reassemble the pieces into a new and compelling manner that others will recognize as art. But the work of art must contain ‘passion.’ It must be a work of ‘love.’ He or she must be in a nearly ‘orgasmic’ state to produce it. Our word enthusiasm comes form Dionysian enthousiasmos, a wild state of holy inspiration. Orgasm is a right-hemispheric function. Love is rooted in the right brain. Ecstasy is an emotion experienced at the right of the corpus callosum (100-101).”
His impressive maps were in part drawn on Ptolemy’s Geographia, but he was also a mountaineer. His aerial views may well have been part visionary, part actual, part imaginary, like so much of his work (image below in Nathan and Zöllner: 484-5). Shlain suggests that Leonardo practiced remote viewing to get these views on paper. I will not discount the possibility of non-local perception, given the extent of Leonardo’s bilateral dominance, with enhanced right-hemispheric functioning.
Leonardo also did more drawings than paintings when usually the reverse is true for artists (Nathan and Zöllner: 12). An enormous percentage of his works has been lost and no studies remain for the Mona Lisa (Nathan and Zöllner: 16). What is especially interesting to me is his visuo-spatial capacity. Rather than drawing from a model, he was often drawing on memory alone and actually sought out certain faces on the street to be captured on paper only after returning to his study.
- Leonardo’s systematic studies of living and nonliving forms amounted to a science of quality and wholeness that was fundamentally different from the mechanistic science of Galileo and Newton. At the core of his investigations, it seemed to me, was a persistent exploration of patterns, interconnecting phenomena from a vast range of fields (Capra: xviii).
- One and the same soul governs
these two bodies; and the desires, fears, and pains are common to this creature
as to all other animated parts. . . . The soul of the mother . . . in due time
awakens the soul which is to be its inhabitant. This at first remains asleep
under the guardianship of the soul of the mother who nourishes and vivifies it
through the umbilical vein (in Capra: 254).
Capra says succinctly: "Never again . . . was so much intellectual and artistic genius embodied in a single human being (259)." Leonardo apparently agreed, acknowledging about himself:
