The most recent writers on genius, creativity’s greatest manifestation, agree that it can appear at any point in the life cycle, not just in childhood. They reject the nineteenth-century romantic belief that it exists only in a small set of heroic people. They find three factors key to what they see as a more general phenomenon. First is a grandiose and mystical sense of the world, what Einstein called “cosmic religiosity.” Such an elevated mood can appear in the hypomanic phase of the up-down cycle of someone with a bipolar disorder, as depression lifts and elation appears. The second element of genius is an ability to concentrate obsessively on a goal and to strive for perfection in reaching it. The third element is a resonance to one’s historical era, being in sync with current ideals, living when one’s gift or invention can be appreciated.5
