This means, no more and no less, that retrogressive development will occur everywhere the influence of science is active. Therefore, for lack of the supply of qualigen, mental abilities will constantly deteriorate in step with the progressive rise in the quantity of living flesh. People will become imbecilic, vegetative and the lower orders of life will atrophy and little by little will cease to exist, because the relatively highest energy-concentrate, the 'upwardly radiating', is missing, which manifests and declares itself as 'Life'.
