The heart of creativity lies exactly there: the heart.
The Latin root for create is creõ, which means “belief”. The Indo-Proto-European root for creõ is cor-, which means “heart”.
It is not thought that moves man into great action, not merely ideas that imbue mind with clairvoyant insight; it is the heart. There we find man’s inner chambers flooded with ecstasy or anguish, the impetus of evolution. Necessity—who is the mother of invention— breeds struggle; we are not born adapted to this world. Struggle shapes our constitution, our capacities, and through this struggle our strength and fortitude is born.
Where there is no feeling, no passion, no pain: there is no creation. Anxiety is the greatest struggle. It is struggle internalized, adopted by the psyche, embodied by the ever reflective mind searching for resolution. It is the single source of genius. Anxiety, or more poignantly, existential angst, is the overwhelming flux of feeling much. It incarnates as a loss of certitude, a banishment of reliable logic, formalized answers. It is accompanied by a frenzied mania chasing for vivification, for illumination and elucidation. It shuns what is presented and rejects the status quo.
Creativity is the enterprise of evolution. The greater the struggle, the greater the chances for unsurpassed evolutionary advantage. Necessity alone breeds innovation: it is an impasse that can only be surmounted by a reflective mind that seeks for its answers inside itself, rather than outside itself, within the world.
Among mankind, the mind has shouldered the responsibility for evolutionary adaptation. No longer do we succumb to the necessities of the physical world. Instead we project our lavish visions of a world modified according to our liking, to our internal ideals. We have inverted the tables of evolution from a wholly extrinsic force to one that is intrinsically borne from the will to power; that is, the will to imbue our influence, our mindful vision, into the world. For the creators, the self-willed autonomous agents: Nature no longer manipulates man: it is man that manipulates nature. Humanity has stretched beyond the zenith of possibility. We become the master by programming our will into the world, by leveraging our values through information and knowledge to suit our desired ends, to manifest our will to power.
Because evolution has transcended physical constraint by occupying the multifarious magnitude of mind, our struggles are no longer physiological, but psychological. That is why anxiety is the greatest virtue of genius. It is the psychologically imposed feeling of struggle that grants passion room for creative invention, for the obdurate heart of crushing genius to reformulate the rules of the game, the laws of society and nature, to transcend the existential angst imposed by the struggle rendered from change.
