Man and Sin by Piet Schoonenberg (1964) 2.3 AQ
[How did the metaphor apply to the person?
One can imagine a thinkdivine that calls the person to attend to the bones. Attend to the scaffolding, the structure that holds one together. The bones give earth to the flesh.
One can imagine a thinkdivine that calls the person to attend to the blood, the warmth and humidity in the flesh. The flesh is weak and vulnerable. Blood balances fire (heat, dryness) and water (coolness, wetness), making the flesh strong and capable.
So far, this metaphor covers earth, water and fire.
One member of the four elements is missing.
‘The air’, ‘the breath’, or ‘the spirit’ is the unspoken complement to ‘blood and bones’. Something invisible from outside ourselves must be taken in, else the flesh dies.
The image of the air reverberates with thinkdivine.]
