“ No one can surely know what knowledge is without the presence of truth.”

“To know how to put what knowledge in which place is wisdom (hikmah). Otherwise, knowledge without order and seeking it without discipline does lead to confusion and hence to injustice to one's self.”

“To know oneself is, above all, to know what one lacks. It is to measure oneself against Truth, and not the other way around. The first product of self-knowledge is humility . . .”

“We confess knowledge without certainty, truth without objectivity.”

“Where secrecy is known to exist one can never be absolutely sure that he knows the complete truth." Edward U. Condon”

“Under the discipline of unity, knowledge and morality come together. No longer can we have that paltry 'objective' knowledge so prized by the academic specialists. To know anything at all becomes a moral predicament. Aware that there is no such thing as a specialized effect, one becomes responsible for judgments as well as facts. Aware that as an agricultural scientist he had 'one great subject,' Sir Albert Howard could no longer ask, What can I do with what I know? without at the same time asking, How can I be responsible for what I know?”
