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)

    There’s not a note of mine that’s worth the noting.
    William Shakespeare (1564–1616)
