As a parent of young children, I have recently come to know that lots of people find it acceptable to lie ("not telling the absolute truth") to children about all kinds of subjects. It is not only that they don't tell them there is no Santa Claus, they actually tell them that Santa Claus exists when children believe it's only a story, and they tell them that it is Santa Claus who gives them presents in Christmas. People tell 5 year old children that "if Mom and Dad really want it, a baby will appear inside Mom's belly". I once heard a Kindergarten "teacher" (can't find the right English word) telling a 3 year old that the broken tail of a plastic cow would grow again. I wonder if all this lying is acceptable? Perhaps there are some empirical, non philosophical issues here (how do children react to coming to know the truth about these things, and to coming to know that adults lied to them?; will this predispose children to lie when they grow?), but even if there are no bad distant consequences to this kind...
