Famous quotes containing the word lead:
“It is not stressful circumstances, as such, that do harm to children. Rather, it is the quality of their interpersonal relationships and their transactions with the wider social and material environment that lead to behavioral, emotional, and physical health problems. If stress matters, it is in terms of how it influences the relationships that are important to the child.”
—Felton Earls (20th century)
“Reading, solitude, idleness, a soft and sedentary life, intercourse with women and young people, these are perilous paths for a young man, and these lead him constantly into danger.”
—Jean-Jacques Rousseau (1712–1778)
“For some years now, there has been proof that the devastating effects of the traumatization of children take their inevitable toll on society—a fact that we are still forbidden to recognize. This knowledge concerns every single one of us, and—if disseminated widely enough—should lead to fundamental changes in society; above all, to a halt in the blind escalation of violence.”
—Alice Miller (20th century)
