I forget in what book or article I first read that flying and flight and airplanes often resonate with the sensibility of the archetypal puer aeternus.
To learn second hand about the puer aeternus is to find out lots about it’s, apparently, inevitable morbid, suicidal side. For example, from the linked essay:
The Puer’s main pursuit in life is ecstasy, many times at the expense of everything else.. This can be externalized in a highly symbolic fashion in fascination with flying or climbing mountains. Many Puers hang out on ski slopes and racetracks. Many are drawn to drinking, gambling, pornography and drugs to get that rush.
A big chunk of the literature of the problem of the puer brings to the front the several varieties of dark, two-dimensional prospects on offer for the indeterminate “many.” (But, not all, of course–although the Analytic Psychology doesn’t traffic in actual evidence aimed to make this distinction.) Still, what about the rest of the puer population? We muddle down the middle between ecstasy and obligation.
