Rationalism
“Is God the ultimate mystery, or the ultimate answer? If you can’t understand God, why would you worship him? You have, by your admission, no idea what you are worshiping. In fact, it’s clear from the history of Abrahamism that billions of people have worshiped the Devil and called him God. They would of course not have made this fatal error if they had understood God.” Rob Armstrong
Your God, I’m guessing.
“Premodern traditions of knowledge such as Islam, Christianity, Buddhism and Confucianism asserted that everything that is important to know about the world was already known. When modern culture admitted that there were many important things that it still did not know, and when that admission of ignorance was married to the idea that scientific discoveries could give us new powers, people began suspecting that real progress might be possible after all.” Yuval Noah Harari
They still do, of course. And the good news being that merely believing what they do “in their head” about religion is what makes it true.
“In this task of freeing my mind of superstitions, Ivekananda was of great help to me. The religion that he preached——including his conception of Yogawas based on a rational philosophy, on the Vedanta, and his conception of Vedanta was not antagonistic to, but was based on, scientific principles” Subhas Chandra Bose
Can anyone really doubt this?
“It is clearly the result, not of carelessness but of matured judgement of our age, which will no longer rest satisfied with the mere appearance of knowledge. It is, at the same time, a powerful appeal to reason to undertake anew the most difficult of its tasks, namely that of self-knowledge, and to institute a court of appeal which should protect reason in its rightful claims, but dismiss all groundless pretensions, and to do this not by the means of despotic decrees but according to the eternal and unalterable laws of reason. This court of appeal is no other than the critique of pure reason itself.” Immanuel Kant
Serious philosophy, let’s call it.
“Even if someone were to write extensively about economics, as Karl Marx did in ‘Das Kapital,’ the truth is that, ultimately, ‘the reality of the world is determined not by economics, but in the last instance by genetics.’” Maitreya Maitreyan
Or, if you count memes, the next to last instance.
“They were bright, confident and fervently dedicated to the cause. Rationalism had become something of a religion to them. It provided purpose, structure and philosophy without all the bells and incense or blood turned to wine.” Tarquin Hall
Until they bump into someone like me?
