“Suffering is admittedly one of the central problems of human existence; but this is because we have a suspicion that it is all for nothing. If we had a certainty about meaning, the suffering would be bearable. With no certainty of meaning, even comfort begins to feel futile.”

"The Holy Dimension", p. 330
Moral Grandeur and Spiritual Audacity: Essays (1997)
Context: Faith is sensitiveness to what transcends nature, knowledge and will, awareness of the ultimate, alertness to the holy dimension of all reality. Faith is a force in man, lying deeper than the stratum of reason and its nature cannot be defined in abstract, static terms. To have faith is not to infer the beyond from the wretched here, but to perceive the wonder that is here and to be stirred by the desire to integrate the self into the holy order of living. It is not a deduction but an intuition, not a form of knowledge, of being convinced without proof, but the attitude of mind toward ideas whose scope is wider than its own capacity to grasp.
Such alertness grows from the sense for the meaningful, for the marvel of matter, for the core of thoughts. It is begotten in passionate love for the significance of all reality, in devotion to the ultimate meaning which is only God. By our very existence we are in dire need of meaning, and anything that calls for meaning is always an allusion to Him. We live by the certainty that we are not dust in the wind, that our life is related to the ultimate, the meaning of all meanings. And the system of meanings that permeates the universe is like an endless flight of stairs. Even when the upper stairs are beyond our sight, we constantly rise toward the distant goal.

Context: But what I really believe is that both he and Mr Wong are innocently guilty of the twentieth century fallacy that technology can be applied to the conduct of human affairs. They cannot believe that anything can work efficiently unless it has been programmed by a computer and have lost faith in the forces of the market and the human actions and reactions that make it up. But no computer has yet been devised which will produce accurate results from a diet of opinion and emotion. We suffer a great deal today from the bogus certainties and precisions of the pseudo-sciences which include all the social sciences including economics. An article I recently read referred to the academic’s “infernal economic arithmetic which ignores human responses”. Technology is admirable on the factory floor but largely irrelevant to human affairs.

2000s, Thus Spake Stallman (2000)
Context: Religious people often say that religion offers absolute certainty about right and wrong; "god tells them" what it is. Even supposing that the aforementioned gods exist, and that the believers really know what the gods think, that still does not provide certainty, because any being no matter how powerful can still be wrong. Whether gods exist or not, there is no way to get absolute certainty about ethics. Without absolute certainty, what do we do? We do the best we can. Injustice is happening now; suffering is happening now. We have choices to make now. To insist on absolute certainty before starting to apply ethics to life decisions is a way of choosing to be amoral.
