We can conceive of no ultimate limit beyond which a thing cannot become either hotter or colder, there is no limit; there are degrees of heat and cold, but there is no heat so great that we cannot fancy its becoming a little hotter, that is we cannot fancy its not having still a few degrees of cold in it which can be extracted.

Context

“Matter and mind are as heat and cold, as life and death, certainty and uncertainty, union and separateness. There is no absolute heat, life, certainty, union, nor is there any absolute cold, death, uncertainty or separateness. We can conceive of no ultimate limit beyond which a thing cannot become either hotter or colder, there is no limit; there are degrees of heat and cold, but there is no heat so great that we cannot fancy its becoming a little hotter, that is we cannot fancy its not having still a few degrees of cold in it which can be extracted. Heat and cold are always relative to one another, they are never absolute. So with life and death, there is neither perfect life nor perfect death, but in the highest life there is some death and in the lowest death there is still some life.” source
