"The material substance of Mind is an all pervading ether which is indivisible, inseparable, indestructible, unalterable and unchangedable; but potentially it contains the appearance of all these dimensions of separability in the states of motion which register the dynamic process of thinking.
"The temperature in the wake of the steamer is higher than that of the surrounding water. Similarly the temperature of the spiral nebula is higher than that of the surrounding "ether" matter, because of the heat energy generated by thinking and transferred to the whirling spheres."
"When giant suns have radiated their heat to the absolute zero of the surrounding ether substance of Mind, they cease all appearance of individual existence. Their forms have disappeared with the cessation of motion, but their substance is as eternal as Mind is eternal."
"Man's speed of light is the speed at which that state of motion-in-opposition, known as incandescent luminosity appears to travel through those high octaves of integrating matter which man calls "empty space," or the "ether of space." This measure of light is but the high measure of a great range of apparent speeds."
"Man has to do with illusion during those periods in which he is forming the idea of himself as illusion; so, therefore, it is necessary that he shall understand the dimensions of the universe of illusion in order that he may control them.

NOTE: Russell used the term "ether" early on in his writings. It is presumed he was 'beat up' by the science community for using this term. In his subsequent writings he leaned towards using the term "unit" in many variations. A wiki page has been started to log Russell's use of the "ether" and "unit" chronologically to ascertain when he switched. Maybe there is a clue as to why he switched. [See Russell - Ether to Unit]
