Think & Share
The mre we knw, the mre we feel ur ignrance; the mre we feel hw much remains unknwn. (Humphry Davy)
Pint f view
I can nt agree with the saying mre.
Argument
Take reading fr example. The mre yu read gd bks, the mre shallw yu will feel, and the less when yu realize that yu knw t little, yu will actively d mre reading. On the cntrary, thse wh have read fewer bks ften think that they knw a lt, but they d nt realize that the cean f knwledge is endless. As the saying ges, “My life is limited while knwledge is infinite.”
