Looks to me like some people are trying to make up some pseudo-philosophical quotes that will make the idiots feel good about themselves.
I mostly agree with this, especially since I think it's all wrong anyways...
First off: Mankind has always and will always be the greatest danger to mankind (imo cuz of the almost complete lack of empathy is almost everyone, but I digress)
Second: Calling the human mind "too powerful and dangerous" is like saying "this computer's cpu is so fast that its dangerous". Sure, that power could be put to dangerous uses, but the users should be judged, not the tool. Which would be the "feel" shit they're talking about. Humans feelings are almost always what govern the usage of our minds, which would imply that human's feelings are too powerful and dangerous opposed to the mind.
Third: Training your mind is a much more substantiatable (ha firefox doesn't recognize this as being a real word) method than "training your feelings" people arent gonna go to college to attain emotional mastery, not only does that sound dumb, but where would you even start? Monk training? So sure keep in mind that you're capable of more than just thinking, but as Ace stated, every process in the human body is run from those thoughts that "are just a very small and temporary part of us"
I also find that site lol, thinking about shit you dont need to bother thinking about is cool and all, but how bout putting your minds to more realistic goals? you know like something that people might actually benefit from? Philosophy is probably the most worthless human invention, right next to religion(or the same thing depending on how you look at it)
