“[T]here is a tremendous egotism and conceit in those popular articles and lectures entitled,"My Idea of Religion," or "My Idea of God." An individual religion can be as misleading and uninformed as an individual astronomy or an individual mathematics.”

Lecture XX, "Conclusions"
1900s, The Varieties of Religious Experience (1902)
Context: The pivot round which the religious life... revolves, is the interest of the individual in his private personal destiny. Religion, in short, is a monumental chapter in the history of human egotism. The gods believed in—whether by crude savages or by men disciplined intellectually—agree with each other in recognizing personal calls. Religious thought is carried on in terms of personality, this being, in the world of religion, the one fundamental fact. To-day, quite as much as at any previous age, the religious individual tells you that the divine meets him on the basis of his personal concerns.

1900s, Hind Swaraj (1908)
Context: In reality there are as many religions as there are individuals.... Religions are different roads converging to the same point. What does it matter that we take different roads, so long as we reach the same goal. Wherein is the cause for quarrelling?

The Artful Universe (1995)
Context: If a 'religion' is defined to be a system of ideas that contains unprovable statements, then Gödel taught us that mathematics is not only a religion, it is the only religion that can prove itself to be one.<!-- Ch. 5, p. 211

Progress In Religion (2000)
Context: I am neither a saint nor a theologian. To me, good works are more important than theology. We all know that religion has been historically, and still is today, a cause of great evil as well as great good in human affairs. We have seen terrible wars and terrible persecutions conducted in the name of religion. We have also seen large numbers of people inspired by religion to lives of heroic virtue, bringing education and medical care to the poor, helping to abolish slavery and spread peace among nations. Religion amplifies the good and evil tendencies of individual souls.
