Famous quotes containing the word safety:
“There is always safety in valor.”
—Ralph Waldo Emerson (1803–1882)
“If we can find a principle to guide us in the handling of the child between nine and eighteen months, we can see that we need to allow enough opportunity for handling and investigation of objects to further intellectual development and just enough restriction required for family harmony and for the safety of the child.”
—Selma H. Fraiberg (20th century)
“Can we not teach children, even as we protect them from victimization, that for them to become victimizers constitutes the greatest peril of all, specifically the sacrifice—physical or psychological—of the well-being of other people? And that destroying the life or safety of other people, through teasing, bullying, hitting or otherwise, “putting them down,” is as destructive to themselves as to their victims.”
—Lewis P. Lipsitt (20th century)
