A metaphysical argument against objectivism in 1 - Metaphysics Posted September 30, 2012 · Report reply Regarding O'ist Metaphysics, it's not so much that I'm disputing anything, more that I find it a bit vague. I've no problem with the law of identitiy per se, it's the relation of it to cause and effect which I find fuzzy. Sorry, I know that's vague, I'm re-reading parts of OPAR and ITOE and I'll get back to you with something more concrete, hopefully.Hi Davy,I think you will find that NB writes more to the point on causality than AR. I'm sorry I don't have my references handy but you will find a page or two on causality in Branden's The Psychology of Self-Esteem. NB also briefly discusses the idea of metaphysical dualism in one of his later books (might be The Art of Living Conciously...I think MSK referenced it recently) and mentions that AR was in agreement with his thoughts in this area. Here he suggests that consciousness and matter may both emerge from a common underlying substance. While still vague, this is a step pointing the direction of their metaphysical thinking.I have spent a lot of time thinking on the issues of causality myself from the starting point provided by AR and NB. From my view, if "what a thing is determines what it does" then there is no need to look for an outside cause. There is no need to look for a first cause or a Prime Mover. AR and NB were suggesting a fundamental shift in how we understand the nature of causation. When we move from seeing causation as a relationship between the action of one thing and the action of another thing to a relationship between what a thing is and what it does, everything changes. It is a fundamental paradigm shift. The need for a Prime Mover comes from a different view of causality from AR and NB's. The question doesn't even come up in the story line of their worldview.PaulHi Paul,Thanks for the feedback. After a bit of Googling I found this, which seems to more or less sum up what you're saying?
