The purpose and usefulness or otherwise of your various notions is within your own perspective the furtherance of various goal, direct or reactive, short or long term, more or less self-regarding etc., but as paradigms their significance is purely 'chemical', as adding just so much of a certain flavour, colour, potency or catalytic effect to compositions in which your intentions play no role at all, apart from said flavour or colour.
