"What is that?"

"That it is cold," said Mordel and tossed it away.

"'Cold' is a relative term."

"Yes Relative to Man."

"But if I were aware of the point on a temperature scale below which anobject is cold to a Man and above which it is not, then I, too, wouldknow cold."

"No," said Mordel, "you would possess another measurement. 'Cold' is asensation predicated upon human physiology."

"But given sufficient data I could obtain the conversion factor whichwould make me aware of the condition of matter called 'cold'."

"Aware of its existence, but not of the thing itself."

"I do not understand what you say."

"I told you that Man possessed a basically incomprehensible nature.His perceptions were organic; yours are not. As a result of Hisperceptions He had feelings and emotions. These often gave rise to otherfeelings and emotions, which in turn caused others, until the state ofHis awareness was far removed from the objects which oiginally stimulatedit. These paths of awareness cannot be known by that which is not-Man.Man did not feel inches or meters, pounds or gallons. He felt hear, Hefelt cold; He felt heaviness and lightness. He _knew_ hatred and love,pride and despair. You cannot measure these things. _You_ cannot knowthem. You can only know the things that He did not need to know:dimensions, weidhts, temperatures, gravities. There is no formula for afeeling. There is no conversion factor for an emotion."

"There must be," said Frost. "If a thing exists, it is knowable."

"You are speaking again of measurement. I am talking about a qualityof experience. A machine is a Man turned inside-out, because it candescribe all the details of a process, which a Man cannot, but it cannotexperience that process itself as a Man can."

"There must be a way," said Frost, "or the laws of logic, which arebased upon the functions of the universe, are false."
