  1. Not to change the most recent subject matter posted, but my neighbor just earlier today stated that the very idea of human activity causing global warming is something that has been completely fabricated... that it's absurd & unrealistic... By the tone of his voice, he was quite passionate about it. I asked him if he thought global warming was even possible? He said 'not by us' I then asked him if he knew about the fact that Venus is hotter than Mercury, because of "runaway" global warming He didn't know about it and did not care to hear that global warming on Venus is very real indeed. I then told him that Venus was hot enough to melt lead, at night or daytime, whereas Mercury's daytime temperature wasn't even as hot as Venuses night temp - & that Mercury's night temperature was 1000 degrees colder than Venuses -- ALL DUE TO THE REALITY THAT VENUS HAS EXTREME "RUNAWAY" GLOBAL WARMING & CURRENTLY INHOSPITABLE HOT HOUSE CONDITIONS. As for global human activity making any impact on global temperatures -- just consider the fact that since the very first motor was turned on (at the start of the industrial revolution) -- that in all that time (100+ years) - there has never been a moment that one or the others had not been running, continually, exhausting emissions into Earth's atmosphere.- NON STOP! for over a century!... Well, that has to have had some kind of impact, considering a single car running inside of a closed garage, can kill us in how short of time? Plus, Global dimming effects haven't even been considered here. Without this opposite phenomenon occurring alongside global warming -- then temperatures today would be MUCH HOTTER! There are much more facts that all together -suggests that human caused global warming is most certainly very REAL. JTM
  2. The following statement comes from Rand's book: Intro to Objectivist Epistemology - With certain significant exceptions, every concept can be defined and communicated in terms of other concepts. The exceptions are concepts referring to sensations, and meta-physical axioms. --- - Sensations are the primary material of consciousness and, therefore, cannot be communicated by means of the material which is derived from them. The existential causes of sensations can be described and defined in conceptual terms (e.g., the wavelengths of light and the structure of the human eye, which produce the sensations of color), but one cannot communicate what color is like, to a person who is born blind. To define the meaning of the concept "blue," for instance, one must point to some blue objects to signify, in effect: "I mean this." Such an identification of a concept is known as an "ostensive definition." OSTENSIVE definitions are usually regarded as applicable only to conceptualized sensations... Consider trying to define red to a blind person???? What is the dictionary definition of the word red?? it is, the color red! There exist no other terms to describe it Also, you'd face the same situation, should you try to define noise to a person that has been deaf from birth? not possible! JTM The following utube videos directly address this matter (conceptualized sensations) Vsauce: Is my red the same as your red? Tommy Edison is blind from birth. In this video he tries to understand color. From his perspective, our descriptions of colors MAKES NO SENSE WHATSOEVER! explaining colors to a blind person: https://www.youtube.com/watch?v=91VUFVp1eXk describing intangible concepts to a blind person: https://www.youtube.com/watch?v=NGYLAKYNVX8&ebc=ANyPxKoSU8V2BOBMuRtKrP48Gp7PY0b9hJKg_0OtY1HIPmDgW1Uu6Ahd11j_QSXgmphtoTPKUNaZGcNaEZTgcwxnHYDpjQ-roA&nohtml5=False colorblind people seeing colors with special glasses: https://www.youtube.com/watch?v=csx_PHKJei8&ebc=ANyPxKorgGFh40hxxIa9wQieY9s8V0gAkLHKhswr_u9ZZXzMSgHeZAqEFX_3uhEnJejqzTQAo0X8xgTRn-jQtw4nXxY0grOoUg&nohtml5=False Young girls sees colors for first time https://www.youtube.com/watch?v=HUuH3itKZ8E man sees a colorful sunset for fist time and is moved to tears: https://www.youtube.com/watch?v=hCiP5bo4j4E&nohtml5=False man sees colors for fist time and then is shown which colors are which (he is conceptualizing colors for the first time ever!): https://www.youtube.com/watch?v=jkyd-wNuFsw&ebc=ANyPxKrgLQ53ZBUBLzDl3dVDrBGp3YpvBFPyFPkjkooPedrXthySJHWWUlKwHyxLoGky-XeZ07ZV4DrsYr7TbT1jfnE9xiBg-Q&nohtml5=False recieving en-chroma glasses (speaking in foreign language - Italian) yet you can still relate to; and understand the universal reactions. https://www.youtube.com/watch?v=ZjBP8U1BwEI&nohtml5=False Video compilation of individuals hearing for the first time ever! an emotional tear jerker!
