 A related debate concerns the authority of parents to control their child’s education. Most discussion of this issue has focused on religion-based objections to the duration or content of public schooling. This was the context in which Feinberg originally discussed the child’s “right to an open future,” which he regards as a constraint on parental discretion regarding their child’s schooling (1980, see below for further discussion). A key challenge is how to justify these objections. One strategy is to cite the parents’ right to freedom of religion, but then some argument must be given for why the apparent interests of a child in being educated should be sacrificed to their religious freedom. A separate question regarding parental rights and education is whether parents are ethically permitted to confer advantages on their children through private schooling, particularly when doing so is expected to reduce the quality of education available to other children (Swift 2003).
