On War & Peace and Wasted Potential: Wars waste people, and all their individual potential bleeds out on the ground as they die; but wars also stimulate technological growth at an astronomical rate, and since The Human is only fully human as it answers the call to technology, perhaps Peace Treaties waste more human potential than wars do.

On the Mathematical Models of the Universe: Math and math models are part of reality, but when a physicist or philosopher forgets that its a model and not the reality itself, precisely there is where a problem arises.

Although there is always an electrochemical state (or more accurately, some parameters of quite a number of them) within the brain (and other bodily chemicals too) that goes along with happiness, it is an error to reduce happiness to these physical states and chemicals. Happiness is the feeling a being experiences as those appropriate physical conditions are present. It is similar to trying to reduce the experience of seeing a beautiful blue sky to the exact measurable wavelengths of light that correspond to the hue; but in the same way, the blue is seen and experienced, whereas the numerical value in no way captures the experience of the viewer. This is the nuts of the metaphysical materialism error; fallacious reductions and an erudite artificial-stupidity that follows them by deductive necessity. Western philosophy is a wonderful means of exploring dead ends and box canyons of thought, and I personally find it to be my second favorite way to pass the time between now and whenever I happen to die, right after fishing.
