All of your thought is developed from patterns of succession, if this then that, if that then this, or call it the principle of sufficient reason, which is another way of saying it's drawn from evolutionary imperatives and so is relative and tactical; what works not what is. The sole exception is knowledge of being, not the realisation that 'you are' since the 'you' is only a causal or social idea, or that 'it is' for the same reason, but simply being. You can verify it at any moment, but can't think it. If a thought corresponds to it, it is the poorest of thoughts. You cannot rightly understand this, it is not to be understood, but is all the more 'real' or 'absolute' for all that. The curious thing is that this radically unthinkable truth has enormous repercussions in thought, in its structure and content, and these effects are both synchronic (phenomenological anthropology) and diachronic (history of being). Tracing these effects does not however constitute thinking being.
