observe, because the underlying reality is invisible. But while the Aristotelian model is thoroughly discredited, I should note that even though matter is not made up of four elements, it does occur in four states: plasma (fire), solid (earth), gaseous (air), and liquid (water). Coming up with a more precise description doesn't mean that the original description is without merit - it's just that typologies (like zoologies) are a first step in classifying things with enough clarity that one can even begin to talk about them.[/QUOTE]
Agreed. Up to now, despite having its roots in psychoanalytical theory, in point of descriptives typology has more resembled the structuralism and functionalism in early psychology in many ways, particularly structuralism in its methods. Perhaps now we will see an expedited evolution in description of the theory as it catches up in its use of modern methods.
