State |
| Definitions |
The usefulness of 'State' is that it makes it possible to describe the evolution in time of an 'Existent' in terms of series of 'State'-s that can take into account the disappearance or appearance of parts within a 'Physical'. A 'State' is a recognizable granularity level of matter, in the sense that its direct parts do not appear or disappear within its lifetime as it can be for a generic 'Existent'. The definition of 'State' implies that its spatial direct parts (i.e. 'physicals') are not gained or lost during its temporal extension (they exist from the left to the right side of the time interval), so that the cardinality of spatial direct parts in a 'State' is constant. This does not mean that there cannot be a change in the internal structure of the 'State' direct parts. It means only that this change must not affect the existence of the direct part itself. There is no change in granularity or cardinality of direct parts of a 'State'. The use of spatial direct parthood in 'State' definition means that a 'State' cannot overlap in space another 'State'. Direct partitions declaration is a choice of the ontologist that choses the classes to be used as direct parts, according to its own world view. A 'State' can always be direct partitioned in 'Elementary'-s and 'Void' or 'Physical'. e.g. the water in my glass can be seen as a single object without declaring direct parts, or as made of H2O molecules direct parts. There is no change in granularity or cardinality of parts within a state. The use of spatial direct parthood in state definition means that a state cannot overlap in space another state that is direct part of the same whole. A 'Physical' which is a tessellation of spatial direct parts. e.g. the existent in my glass is declared at t = t_start as made of two direct parts: the ice and the water. It will continue to exists as state as long as the ice is completely melt at t = t_end. The new state will be completely made of water. Between t_start and t_end there is an exchange of molecules between the ice and the water, but this does not affect the existence of the two states. If we partition the existent in my glass as ice surrounded by several molecules (we do not use the object water as direct part) then the appearance of a molecule coming from the ice will cause a state to end and another state to begin. |
