W. M. Flinders Petrie,
Ten years' digging in Egypt, 1881-1891
“ One may be following the outside of a fortification, another trenching across it to find its thickness, another sinking a pit inside it to find the depth of the soil, another clearing a room, or trenching to find the limits of the town, or removing a rubbish deposit layer by layer. Unless just beginning work on a very featureless site, the aimless trenching or pitting is merely an excuse for a lazy mind. Far better have some theory or working hypothesis, and labour to prove it to be either right or wrong, than simply remain in expectancy. ”
