Conventional science has so far only become acquainted with the forms of heat that exhibit fatiguing effects, which however are those heat-forms through which the resistance to motion increases by the square of the velocity. This occurs for the simple reason that they are precisely the forms of temperature that kill off all dynamism and vitality and which, after a suitable development, are transformed into the condensing (falling and concentrating) cold-forms in order to conduct the thing in question back onto or into the Earth, where under the exclusion of light and heat it is prepared for a renewed attempt to rise.
