Where do abilities of soul and spirit originate? What does the seed look like that becomes visible when transformed into a flower? Why do we see withering and atrophy instead of the awaiting soul forces? Where do the tendencies lie that later appear as physical health or organic disease?… I realize very quickly that, in order to follow the seed’s hidden transformations into flower and fruit, I must transform my thinking itself; I must make it more alive and active. ―Willi Aeppli. Aeppli traces transformations in the life and soul of children and how we can respond to them. He explains their effects on the soul life and organic processes. This essay is also contained in Willi Aeppli’s collection of essays, The Developing Child.
