    The Official Subject Brief




    You shall no longer take things at second or third hand, nor look through the eyes of the dead, nor feed on the spectres in books,
    You shall not look through my eyes either, nor take things from me,
    You shall listen to all sides and filter them from your self… Not I, not any one else can travel that road for you,
    You must travel it for yourself. 

    It is not far, it is within reach,
    Perhaps you have been on it since you were born and did not know…

    — Walt Whitman: From Song of Myself (1855)

    The man bent over his guitar,
    A shearsman of sorts. The day was green. They said, “You have a blue guitar,
    You do not play things as they are.”

    The man replied, “Things as they are
    Are changed upon the blue guitar.”

    And they said then, “But play, you must,
    A tune beyond us, yet ourselves,

    A tune upon the blue guitar
    Of things exactly as they are.”

    — First stanza of “The Man with a Blue Guitar” by Wallace Stevens (1937)

    The human brain craves understanding. It cannot understand without simplifying; that is, without reducing things to a common element. However, all simplifications are arbitrary and lead us to drift insensibly away from reality.
