Yes, I definitely think that 'secret knowledge' is one permutation of what 'esoteric' can mean. An 'agreed truth' within a small community. I don't think this is the 'purer' meaning we've been talking of on the other threads though, which is a self-dissapation through the absence of language.
I thought surrealism was based on a conscious understanding of the sub-conscious. Presenting things that we are normally familiar with to look 'other'; inverted anthropology.
Here is what I wrote today, I'm just going to write it all out without rephrasing it as questions, regardless of how self conscious I am about it being wrong, just in case anyone has any points they could add or reading they could suggest:
'Spirituality/esotericism' as the 'will towards self-transcendence': an extended performance metaphor in an artist's practice, e.g Skriabin or Kandinsky.
When framed with the lust towards this 'other' an artist's emotional invlovment with his/her own creation is heightened; tones, shades, forms, shapes are empowered and therefore can be more easily wrought by the emotions. Thus the will 'towards the other' or lust for the 'beyondness of things creates the best platform for artistry. The 'other world' which lies beyond this world that I mention isn not lucid in the mind of the artist, and cannot be 'truly' represented. If it could e represented then this would destroy the point - for it is its nebulous character that allows it so many permutations in the minds of those who desire it. Rather, it is a dreamed world where one feels form, shape, colour as they do their own body; uninhibited life-force. It is the disillusion of the 'barrier' between the phenomenal and noumenal world on an experimental and sensual level.
Therefore, all artworks that attempt to 'break through' to this world fail; the most they can do is point towards it or 'touch' it. The arts that service the mindset the best are music and abstract painting since they are non-representational.
