One important aspect of [genuine] philosophy is a radical dis-entangling of [all] concepts – separating concepts that have become stuck or lumped together in contemporary discourse or one’s own mind. Points of connection or over-lapping of [extensions of] concepts mustn’t distract from the non-identity and independence of concepts.
an example: [being able to] talk to about reason – the concept of reason – as something value-neutral, i.e. without the whole concept being [intrinsically] joined to the very basic concept of good.
[Metaphorically,] I picture the inside a puff pastry or ciabatta that is rising airily – delicate and beautiful – or lungs filling with a deep breath that leaves no cavity unopened.
Slightly more technically, I suppose this particular formulation high-lights the vertical or depth dimension of thought and theory – and the maximising of this dimension.
