The passage suggests that while skepticism is useful, it is equally important to recognize that some beliefs are vital and advantageous to our well-being. Among these beliefs is the faith in human goodness. The text acknowledges that there are many reasons to doubt the inherent goodness of people, but losing that belief could lead to a lack of trust and comfort in relationships.

This trust is essential for navigating the challenges and disappointments of life. The idea presented is that in order to cope with hardships, individuals need to cling to certain comforting beliefs, such as the goodness of others. Thus, maintaining a level of optimism and belief in humanity can provide the emotional support necessary to face adversities.
