" I am constantly asked: What can you, with your cold rationalism, offer to the seeker after salvation that is comparable to the cozy homelike comfort of a fenced-in dogmatic creed? To this the answer is many-sided.
First, I do not say that I can offer as much happiness as is to be obtained by the abdication of reason. I do not say that I can offer as much happiness as is to be obtained from drink or drugs or amassing great wealth by swindling widows and orphans. It is not the happiness of the individual convert that concerns me; it is the happiness of mankind. If you genuinely desire the happiness of mankind, certain forms of ignoble personal happiness are not open to you. If your child is ill, and you are a conscientious parent, you accept medical diagnosis, however doubtful and discouraging; if you accept the cheerful opinion of a quack and your child consequently dies, you are not excused by the pleasantness of belief in the quack while it lasted. "

― Bertrand Russell
