A principle of unreason

The absolute is the absolute impossibility of a necessary being. We are no longer upholding a variant of the principle of sufficient reason, according to which there is a necessary reason why everything is the way it is rather than otherwise, but rather the absolute truth of a principle of unreason. There is no reason for anything to be or to remain the way it is; everything must, without reason, be able not to be and/or be able to be other than it is.
