Back to the Finchley Central hypothesis

In the late 13th or early 14th century, Eckhart von Hochheim, a German philospher, discussed the following:

So she remained immovable in her detachment, and praised in herself not detachment but humility. And if she had by so much as a word mentioned detachment, and had said: "He has regarded my detachment," detachment would have been troubled by that, and would not have remained wholly perfect, for there would then have being a going out. There can be no going out, however small, in which detachment can remain unblemished.

This appears to be saying that, whilst being detached, if you think about the fact that you are detached, then you are no longer detached.

Thanks to Douglas Allen, Eric Smith, and Andrew Grant from Canada for suggesting this origin.
