The Fourth Dimension

I have always been severely disturbed by the fact that time is generally accepted as the fourth dimension.

Time, unlike the x, y, and z directions, cannot be assigned a vector. David Z Albert's book, Quantum Mechanics and Experience, states: "... the dimension of a space is equal to the number of mutually perpendicular directions in which vectors within a space can point" (Albert, 21). Time, however, cannot be assigned a vector, let alone a perpendicular one. Thus, it cannot define a perpendicular direction, and cannot be counted as a dimension.

More on this argument to come.
