which variables to manipulate, which effects are to be observed and which confounding variables need to be neutralized is the extent to which it is impossible not to adopt something resembling a Kantian Metaphysical Philosophy of Science. Kant's theory contains an architectonic view of the relation of levels of scientific activity. Throwing a rock parallel to the ground produces, argues Kant(after a large number of "experiments") an awareness that the path the rock will be a curvilinear one back to the earth. The reason the path of the rock presents itself as it does to the perceiver will vary in accordance with the variables of the mass of the rock, the velocity imparted by the thrower, the resistance of the medium of the air and the pull of gravity upon the rock. The actual path of the rock, including its velocity, can be calculated mathematically by using the above variable system which is the result of empirical generalizations generated by a large number of experiments. Now we know that Newtonian science called itself natural philosophy and there are sound reasons for this. Newton for example abstracted from one concrete variable, namely the resistance of the air and introduced another transcendental variable of causation, thus postulating two further levels above that of what could be physically observed or experienced. In the first case, Kant called this level metaphysical and in the second he called the level transcendental. Both levels were regulated by logical relations between their elements. The metaphysical level and transcendental levels were in fact well illustrated by Newtons first(logical) law of motion: Every object continues in a state of rest or of uniform motion in a straight line unless acted upon by some other force. A rock thrown in an environment where there was no air resistance or effect of gravity would on this theory continue resting or moving in a straight line: a phenomenon that no one has observed or experienced. This law of motion also incorporates another variable that transcends experience, the variable of causation which is characterized by the proposition "every event has a cause". Such metaphysical and transcendental principles are in fact ways of thinking about phenomena and require nonexperiential nonobservational philosophical and logical justifications. Furthermore, on the Kantian account, this transcendental principle of causation also has an Aristotelian application to forms of life that act as they do in accordance with a principle of internal causation, e.g. a dog jumps over a fence circumscribing as he does to a curvilinear path that is only partly explained by the laws of physics. The other part of the explanation of this phenomenon will refer to the above internal cause, i.e. to the desire and effort of the dog.
