The Spirits' Book
Book Three - Moral Laws
Chapter XII - Moral Perfection
916. Selfishness increases with the civilization that seems to strengthen and intensify it. How can the cause destroy the effect?
“The greater the wickedness the more hideous it is. Selfishness has to do a vast amount of harm, so that you may understand how crucial the need is to eradicate it. When human beings overcome selfishness, they will live like brothers and sisters by mutually helping each other through a sense of solidarity. The strong will then support the weak, rather than oppress them, and no one will lack the necessities of life because everyone will obey the law of justice. This reign of good is what the spirits are responsible for preparing.” (See Q784)
