For the OK, there is in fact no opposition between the logical and the material or the spiritual: reality is a formless logical substance. Representation is morphogenesis and the terms 'material' and 'spiritual' only denote categories of morphogenesis.
Our constant experience shows us that spiritual and material interact. The border between understanding and becoming, between meaning and act, which seems trivial to us, is elusive when we try to approach it. For example: when the subject follows the object of his attention with his gaze, where to draw the line between material and spiritual ?
Representation is morphogenesis and the OK uses the term 'horizon', not to separate the material from the spiritual, but to distinguish the formless from the representable, the unspeakable from the speakable.
For the OK the speakable is not 'something else' than the unspeakable, it is a mode of order: The rainbow is not 'an other thing' than rain, light, sun, the walk that brought me here and now, my sense of vision, my culture etc ... all this unspeakable set of logical interdependencies from which emerges, for me subject, the meaning of the rainbow.
And above all, this horizon is not 'in my mind'. The ordaining of the unspeakable is not carried out 'by my understanding'. The emergence of the meaning from the unspeakable logic is not happening 'in' and 'by' my mind.
On the contrary, it is a process of pure logic*, a progressive aglomeration of interdependance, which makes the subject emerge as a representation of the world and of his own existence.
The logical transcends the Existing.
This is the key to understanding this article:
We have not left the Garden of Eden. The representation is not 'overhanging' the world, it is 'the' world. Representation is not "grasping form" but "morphogenesis", not as "attribution of form" but as "necessary ordering mode of logical reality".
Common sense (including science and logic) does not represent reality, it emerges from it in the form of modes of order of reality, of logic. My representation of this white stone is not 'something else' than the unspeakable logic from which the meaning of 'white stone' emerges for me, it is only a mode of order.
There are no "other things" than the things which represent themselves in me and which are modes of order.
The Existing is representation. Existence is a mode of order *.
The amorphous logical "substance" precedes (transcends) its representation.
The logical transcends logic.
