“The lungs are nothing but wings that have lost their way.” If you consider that light/energy and air are what essentially make our corporeal component, this line is, indeed, the peak of the metaphysical understanding of man. Following the logical conclusion of the Platonic formula for life (we are spirits trapped in ephemeral vessels), breath as we know it are the wings to the ultimate genesis, and the air beneath the wings that make us ascend Icarus-like. Thus, your line as humour but poetic nonetheless, aspires to fulfill its ontological (defining being) and epistemological (discovering knowledge) functions. And I am not even being hyperbolic. I like the series, Dave.
