Persistence and qualitative change The metaphysical idea of and object persisting over time brings rise to a lot of debate on how we can properly identify a thing as it experiences qualitative change over time. The main issue that arises when talking about persistence over time is whether we can identify the initial thing we are observing as a different entity as time progresses and it undergoes qualitative change. For example is some thing we identify as “x”, that goes through a qualitative change at time T1, the same as the thing “x” at time T2 after the change was implemented. There are many different views on this topic and I will introduce three of them and then select the one I think is most probable. The first view is the…show more content…
My initial thoughts about this is that is similar to a mathematical function were you can get a y-value (current state) for every x-value (position in time) and that you only get to see the whole function when you graph all x,y “relations”. Also the direction of the graph can change (qualitative Change) depending on the function. The three problems that arise with this theory is the assumption that the notion of time is non-existent and that a thing can never represent itself at any one time because by the very definition of this theory it would be insufficient in representing itself. The time issue is a consequence of a thing not being a whole thing unless it’s dispersed over time therefor a thing is only itself when time is one “frame”. Using algebra to explain what I mean I can say that an object “Q” is equal to Q only when the sum of all times “t” is equal to 1 because Q is equal to the sum of all Q’s corresponding to all times “t”. The third issue is that it denies that anything changes (by our definition of change as a function of time) because it denies that time is ongoing. This theory is not empirically supported because obviously we see time as being ongoing and infinite also it is an overly complicated explanation for what we seek. The last theory is called the no persistence theory and it states that an object “x” does not persist through time
