This quote by George Herbert talks to the importance of a daddy figure in a kid's life. Herbert is suggesting that a daddy is more prominent and crucial than any number of schoolmasters. A dad is not just a teacher, however a role model, coach, and protector. He is someone who can offer guidance and assistance, and who can help a kid to develop into a responsible and successful adult. A father can provide a complacency and stability, and can help a child to develop a strong sense of self-worth. He can also provide a sense of belonging and connection, and can assist a kid to establish a sense of function and direction. A dad can be a source of genuine love and approval, and can assist a kid to develop a strong sense of confidence. In other words, a daddy is an invaluable property to a kid's life, and is much more important than any number of schoolmasters.
"Children that are raised in a home with a married mother and father consistently do better in every measure of well-being than their peers who come from divorced or step-parent, single-parent, cohabiting homes"
