Principal Note

Famous quotes containing the words principal and/or note:

    There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
    Denis Diderot (1713–1784)

    No, in your rural letter box
    I leave this note without a stamp
    To tell you it was just a tramp
    Who used your pasture for a camp.
    Robert Frost (1874–1963)
