Quote by Robert A. Heinlein
Delusions are often functional. A mother's opinions about her children's beauty, intelligence, goodness, et cetera ad nauseam, keep her from drowning them at birth.
Summary
This quote suggests that delusions can serve a purpose in our lives. Specifically, it highlights the protective nature of a mother's delusions about her children. By holding positive opinions about her children's attributes, such as their beauty, intelligence, and goodness, a mother is able to overcome any negative thoughts or difficulties, preventing harm to her children. In essence, these delusions act as a defense mechanism that allows a mother to care for and value her children unconditionally.
