Childhood
Childhood is the age span ranging from birth to adolescence. According to Piaget's theory of cognitive development, childhood consists of two stages: preoperational stage and concrete operational stage. In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty). Various childhood factors could affect a person's attitude formation.
Ethics
Ethics or moral philosophy is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. The term ethics derives from Ancient Greek ἠθικός (ethikos), from ἦθος (ethos), meaning 'habit, custom'. The branch of philosophy axiology comprises the sub-branches of ethics and aesthetics, each concerned with values.
Philosophy
Philosophy (from Greek φιλοσοφία, philosophia, literally "love of wisdom") is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The term was probably coined by Pythagoras (c. 570–495 BCE). Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? Philosophers also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust (if one can get away with it)? Do humans have free will?
Youth
Youth is the time of life when one is young, and often means the time between childhood and adulthood (maturity). It is also defined as "the appearance, freshness, vigor, spirit, etc., characteristic of one who is young". Its definitions of a specific age range varies, as youth is not defined chronologically as a stage that can be tied to specific age ranges; nor can its end point be linked to specific activities, such as taking unpaid work or having sexual relations without consent.
Philosophy
That stone,
Philosophers in vain so long have sought.
John Milton, Paradise Lost (1667; 1674), Book III, line 600. Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 596-97.
Ethics
I believe, indeed, that overemphasis on the purely intellectual attitude, often directed solely to the practical and factual, in our education, has led directly to the impairment of ethical values. I am not thinking so much of the dangers with which technical progress has directly confronted mankind, as of the stifling of mutual human considerations by a "matter-of-fact" habit of thought which has come to lie like a killing frost upon human relations. … The frightful dilemma of the political world situation has much to do with this sin of omission on the part of our civilization. Without "ethical culture," there is no salvation for humanity.
Albert Einstein, in "The Need for Ethical Culture" celebrating the seventy-fifth anniversary of the Ethical Culture Society (5 January 1951)
Ethics
Strong ethics keep corporations healthy. Poor ethics make companies sick. Values are the immune system of every organisation.
Patrick Dixon, in Building a Better Business (2005), p. 131
