"Friendship is the marriage of the soul, and this marriage is liable to divorce"

This quote by Voltaire speaks to the concept that friendship is a deep and meaningful connection between two people, similar to the bond of marriage. However, unlike marriage, friendship is not legally binding and can be liquified at any time. This quote recommends that friendship is a vulnerable bond that can be broken easily, which it is not always an irreversible relationship. It also implies that relationship is a choice, and that it is up to the individuals included to decide whether or not to preserve the relationship. Ultimately, this quote functions as a tip that relationship is an important and significant connection, but it is not always a lasting one.
