"Man is by nature competitive, combative, ambitious, jealous, envious, and vengeful." ― Arthur Keith Topic(s): Nature More From Arthur Keith "Under no stretch of imagination can war be regarded as an ethical process; yet war, force, terror, and propaganda were the evolutionary means employed to weld the German people into a tribal whole." "My personal conviction is that science is concerned wholly with truth, not with ethics." "In a tribal organization, even in time of peace, service to tribe or state predominates over all self seeking; in war, service for the tribe or state becomes supreme, and personal liberty is suspended." More In Nature "Man is by nature a political animal."― Aristotle "I don’t understand the notion that modern farming is anything do to with nature. It’s a pretty gross interference with nature."― Peter Singer "Suffering is permanent, obscure and dark, And shares the nature of infinity."― William Wordsworth
