In "Morality for Beautiful Girls," Alexander McCall Smith suggests that ignorance can sometimes lead to greater happiness. The quote implies that being unaware of certain harsh realities or complexities of life may protect individuals from unnecessary worry or sadness. By not being burdened by the weight of knowledge, one can appreciate simpler joys and cultivate a more positive outlook.

This perspective challenges the common belief that knowledge is always beneficial. Instead, it highlights the potential advantages of a more carefree existence. Those who choose to focus on the simpler aspects of life may find themselves enjoying their daily experiences without the pessimism that often arises from being fully informed about the world's troubles.
