A major component of these conditions is the environment, which includes the dimensionality of space-time. On the other hand, the ability of the brain to perceive the dimensionality of space-time may be limited by some inherent properties of the brain, and our perception of dimensionality may be inaccurate. I explore here the possibilities that this dimensionality is actually different from 4. In particular, the possibility of 2 dimensions of time and 4 dimensions of space is explored.
