No effect can be conceived of without some primal cause. This light is an effect, but back of it is the energy which is the cause. That is impossible and inconceivable. It is self-evidently false. Accidental composition is, therefore, a false theory and may be excluded.
Humidity is the inherent nature or property of water.
The power of attraction has as its function attractive, or magnetic, qualities. We cannot separate attraction from that power. You cannot separate the effect from the cause. As fire cannot be separated from heat, likewise the elemental being could not be subjected to decomposition, and this does not hold true because we see decomposition everywhere. Hence this theory is untrue, inasmuch as we observe that after each composition there is a process of decomposition which forever ends it.
