NosyNed Anything for a fellow Canuck.
(1) "Without an explanation or an interpretation of the world around us, we would be helpless to deal with reality. We could not feed ourselves, or act to preserve our lives."
The most obvious contradiction of this statement is animals themselves who, without the benefit of metaphysics, deal with reality far better than we do.They both feed themselves and act to preserve their lives.Since we are animals ourselves we too are fully capable of operating without a working philosophy and,indeed did just so for a lot of our history.
(2)The next one is from Existence Exists.
"The very fact that one is aware of something is the proof that something in some form exists"
The fact that one is aware of something is not even PROOF that one is aware of something.It is an agreed upon assumption for the most part as a basis for a starting point to see if anything can be further deduced.What exactly existence is is only found in the minds of egotistical philosophers.There is no guarantee that our science can descibe everything and that even through the proper use of logical construction that everything can be understood.
(3)In questions and answers /Questions from a relativist there is a highlight on the word skepticism which leads to this gem of clarity.
"For example, inductive skepticism claims that induction does not bestow true knowledge. They claim that if you have seen 100 sheep, and they all had ears, you are unjustified in claiming "All sheep have ears" because somewhere out there might be a sheep without ears. Even if you have analyzed all sheep that you can find, there might be another somewhere. Skeptics will claim that only knowledge gained through deduction from known facts is knowledge."
If you wish I will point out the problem with this statement but I need to run some errands for the wife and I have no doubt whatsoever that SHE exists.
