The steam engine, bringing life to vast land areas, sparsely populated, after tracks laid down, stretching for miles. This entire continent – spanned from Los Angeles to New York City – through a network of railway tracks, connecting coast to coast. Each spike placed in the right place; every concrete slab supporting the means for train cars, pulled along by the locomotive (engine car) in front. The tracks serve their purpose, waiting in silence for the next train; supporting tons of steel as the train grinds steel against steel, sometimes sparks flying upwards.
Freud’s entire model of psychodynamics was inspired by the mechanics of the steam engine, as well as the laws of thermodynamics. Freud’s concept of psychic energy was derived in part from, and analogous to the steam that is used to power an engine. The first thermodynamic principle, “energy can neither be created nor destroyed” also played a role in the formation of the conceptual underpinnings of Freud’s theories. Like steam, one of the three forms of water, psychic energy can also manifest in different forms, including neuroses.
Yet, human beings are not machines; nor, are we computers, even though some psychological theories today are based upon a computer model. Rather, like the soulful stirrings of the horn being sounded by an engineer, as a train passes through city limits, the soul itself sounds out against the realities of the world, led by an unseen Engineer. Inasmuch that human beings preceded any invention made by human design, it is reasonable to view the psyche (soul) as part and parcel of the overall design from Above.
