988. What difference can there be between a "created" object's relationship to "something" "infinite" and its relationship to "something" "limited", to "something" "finite" or to "something" "temporal"? First one must become clear about what a "created" object's relationship to another "created" object is. Since a "created" object is a combination of energy, whether it appears in solid, fluid or gaseous matter, and is thus a "type of movement", a "created" object's relationship to another "created" object is in reality the same as a "difference of movement". The one object can be more or less "quick" than the other. Degrees of speed thereby arise. It is these degrees of speed that act on the senses. It is these same degrees that constitute answers in terms of weights and measures and that are in turn the same as answers in terms of effects. Everything without exception that is directly accessible to perception is therefore in reality simply degrees of speed. As speed is in turn the same as "energy", everything that can be sensed is therefore the same as degrees of "energy". But it is not common to express everyday objects that can be sensed in terms of degrees of speed or energy. Only when we are dealing with a material phenomenon that is so clearly marked that its movement can be seen physically, do we express it in terms of degrees of energy or speed. Wherever the movement cannot be seen but is nevertheless present, we indicate its degrees in quite other terms, namely, "time", "space" and "colours". If we say about an object that it is, for example, ten years old, the term "ten years" thus indicates a certain area of energy. "Ten years" acts on the senses more than five does but less than twenty. "Time" is thus a concept of energy. The same thing applies to dimensions. Ten metres acts more strongly on the senses than five does, but more weakly than twenty. Space is likewise a concept of energy. Since colours are similarly concepts denoting energy – if they were not, they could not be sensed – "time", "space" and "colours" are fundamentally merely degrees of energy or speed. Without "movement" and without this in turn being divided into degrees, neither time, space nor colour would exist. All material objects that can be sensed are therefore in reality "concepts denoting speed".
