Not at all , the absence of heat isnt cold, its the lack of any perception of temperature by your brian. To be accurate cold is a subjective relative comparison to heat. Phsiologically, cold is a perception of temperature by the brain after energy is transfered to a nerve cell. A low amount of energy causes us to feel "cold" within a certain range and a higher energy amount causes us to feel heat in a certain range, between the two ranges we feel neither cold nor heat, this is room temperature, and it is what is referred to by the absence of heat or the absence of cold. That is why your analogy is wrong, Hot, cold, and room temperature are all different measurements on a temperature scale, they exist and they exist independently of one another and because of this they cannot be used as an analogy to "nothing" because they are something.
It is entirely possible however, that you are not refering to the human perception of heat but rather to heat and cold independent of human perception (from the skin), meaning that heat is the presence of EM radiation of a certain frequency range in a given space and that cold is the lack of EM radiation of this same frequency range in a given space. While this may be true, you are decieving yourself if you think you are in anyway way saying something different from the original defination. Your post
It's basically the same as saying that cold is merely the absence of heat, and does not "exist" in any sense except to denote absence.
is merely the defination of nothing using a specific concrete, heat, and a lingusitic substitution for nothing, cold, in relation to that concrete. Meaning that your post is just one specific context in which the defination of nothing can be taken. From your post we can easily extract the essence of what you were saying, and this "essence" is basically a compact form of what I orignally quoted from Rand. So if someone where to write a compact defination for nothing it would be:
Basically nothing is the absencse of something, it does not "exist" in any sense except to denote absence.
In conclusion we can say that your example was accurate (assuming you meant the second example of heat and cold
), but too specific. It is certainly worse then the original explanation for this reason, but also because one can become confused by what you mean when you say heat and cold. Finally, I said the original Rand quotation was a good explaination, not that it was a compact defination. A short defination isn't necessarily as good "long-winded" explaination at helping someone understand a concept. Rand explaination is good for explaining nothing to people who are used to thinking of nothing as a given quantiy, such as the person who was quoted at the start of this thread . i.e. having a "little speck" of nothing.
Now then...... ADMIT IM RIGHT WONG!!
