The article argues that the simulation can be furthered by analyzing it using philosophical tools of analysis. Since simulation is a digital/physical representation of they way our mind will perceive and event, it falls within the realm of mind, and thus, the study of philosophy By analyzing simulation using the philosophical method, there is much about the design and implementation of simulation that can be gained.
While I believe that understanding the way the simulation interacts with our cognitive space is very important, I think it is more important to deal with the physical elements of simulation. For example, in a basic video game, you are given either a mouse and keyboard, or a controller, in order to interface with the game. There could be extensive physiological analysis to figure out how to design the game, but in the end, it will still fall short as a simulation purely because of its physical controls.
