I know he would like to slash that defense budget and the republicans know better than to give him the opening in sequestration.I think getting off the wartime economy would do this country great good. Of course a number of weak sisters might have to pay for their own defense. I denoted a aggressiveness in the president and I think he will be a more potent agent for change in this new term. Follow Obama with Hillary and Milt may be on the weed. I want a picture. Bill

        My only point is that the idea of the apple does not "reside" within the
        apple, as you suggested.

        When referring to anatomical differences of receptors, I forgot to specify
        sense organs which are variously configured and influence perception. My
        point is that anatomical variations determine how and what we perceive, yet
        despite these differences some of us are able to grasp the notion an object
        represents and further develop the truth about it.

        An apple is not just an apple; it represents an agricultural and commercial
        history, cultural mythology and symbolism, scientific, nutritional and sense
        properties, relationship with the environment, etc. Furthermore it
        represents how an immediate appearance is mediated as an object for the
        observer and developed into a complex truth.

        The brain is as essential to thought as the objects of thought, including
