 Process philosophy is based on the premise that being is dynamic and that the dynamic nature of being should be the primary focus of any comprehensive philosophical account of reality and our place within it. Even though we experience our world and ourselves as continuously changing, Western metaphysics has long been obsessed with describing reality as an assembly of static individuals whose dynamic features are either taken to be mere appearances or ontologically secondary and derivative. For process philosophers the adventure of philosophy begins with a set of problems that traditional metaphysics marginalizes or even sidesteps altogether: what is dynamicity or becoming—if it is the way we experience reality, how should we interpret this metaphysically? Are there several varieties of becoming—for instance, the uniform going on of activities versus the coming about of developments? Do all developments have the same way of occurring quite independently of what is coming about? How can we best classify into different kinds of occurrences? How can we understand the emergence of apparently novel conditions? Can we conceive of becoming or dynamic being independently of space and time?
