Famous quotes containing the words corps and/or observation:
“Many a woman shudders ... at the terrible eclipse of those intellectual powers which in early life seemed prophetic of usefulness and happiness, hence the army of martyrs among our married and unmarried women who, not having cultivated a taste for science, art or literature, form a corps of nervous patients who make fortunes for agreeable physicians ...”
—Sarah M. Grimke (1792–1873)
“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)
