The Sunnier Side of Doubt

(Article is by guest writer Ed Kelly Jr. See bio below.)

For nothing worthy proving can be proven,
Nor yet disproven,
Wherefore thou be wise,
Cleave ever to the sunnier side of doubt
                             Lord Tennyson[i]

Since leaving the mindset of Fundamentalism, I have been drifting out of the certainty of knowledge into a healthier balance of doubt. My previous worldview was a theocentric revelational view of knowledge rooted in an absolute paradigm that truth is found in one’s traditional interpretation of the religious revelation. My current worldview is quite different, the Naturalist scientific view of knowledge rooted in the principle of rational scientific critical analysis based on questioning, testing, and verification. To be honest, I am still struggling on a daily basis to free myself from the force of my past traditions, the tyranny of my own passions to “be right” and the urge to absolutize beliefs and opinions.    This may be an oversimplification, but as I see it, Fundamentalism focuses on certainty of belief and obedience to the articles of dogma, while Naturalism focuses on doubt and the continual search for scientific answers. Most of my life, I lived in the illusory realm of having complete certainty of my beliefs; presently, I am trying to live my life with a new principle: doubt.

As a Fundamentalist Pentecostal preacher, I proclaimed the necessity of absolute faith – absolute “certainty” about religious beliefs and that doubt was the opposite of faith, the ultimate sin. Usually after every sermon, I would give an altar call always asking the same question: ”If you were to die tonight, would you be absolutely-certain, you would go to heaven?” Looking back, what haunts me, is the phrase “absolutely certain,revealing the fundamentalist mindset.   There was no room for doubt. Today in Evangelical-Fundamentalist Christianity, doubt has been demonized and this demonization of doubt has done considerable damage to our spiritual growth and evolution. Doubt is demonized when we deify and absolutize a religious claim thereby, suppressing criticism and the honest search for answers.

My attitude since has changed to a healthier attitude of some degree of skepticism. Doubt is no longer a taboo but a stimulus, a goad encouraging me to search for more questions and answers.  I am now secure in recognizing that I am only human and I do not have all the answers; which is a far cry from where I use to be, as a Fundamentalist, thinking I had all the answers. One of the components of Spiritual Naturalism is intellectual humility – which means:

“We believe in a humble approach to knowledge. With humility, we can recognize that human beings are imperfect in their ability to know all things. Therefore, we are careful to limit our claims about reality to what we can experience and measure, as well as reproduce and show to others. On all else, we are content to admit “we don’t know”.” [ii]

I am now free to admit without shame “I do not know.” There are several other critical thinking principles that I have put into practice in this search for answers. I am grateful for the writings of Bertrand Russell, 19th Century Philosopher and his principles of “critical undogmatic receptiveness” and “intellectual sobriety” which rejects certainty (the demand for which he calls an intellectual vice) and ensures that open-mindedness does not become mindless.

“The quest for certainty blocks the quest for meaning. Uncertainty is the very condition to impel man to unfold his powers.” [iv]

Some rules on Critical Thinking: [iii]

  1. Do not regard anything that one accepts as certain but only as probable.
  2. Begin forming my own opinions instead of relying on traditions and other authorities.
  3. Readiness to examine my beliefs with an open mind, taking into account and accepting all relevant and new evidence against previous beliefs, a willingness to examine both sides (unbiased) and discard a belief/hypothesis that has proven inadequate or unhealthy.
  4. Learning to recognize and control my bias, which is not easy.
  5. Viewing my beliefs with detachment
  6. Avoid being defensive when my beliefs are challenged
  7. Willingness to acknowledge my mistakes
  8. A willingness to adapt to the facts of the world
  9. Hold on to my beliefs with a degree of conviction warranted by evidence.

Growing up, I was not taught how to think critically, but to believe unquestioningly. I am now learning late in life how to live rationally, as I should, as I am a rational animal.

  1. A compelling spiritual and intellectual journey. There is one valuable point I’d like to mention. Uncertainty drives, in your words, “rational scientific critical analysis.” It also allows, in Erich Fromm’s quoted phrase, “the quest for meaning.” But scientists usually lean away from broad claims about “meaning.” They like to remind us that their rigorous process offers solid information and probable theories but not meanings or morals or answers. But the difference between the two is relative. Compared to the closed-mindedness of Fundamentalism, hard science and spiritual naturalism are first cousins.

  2. Brock, that is a good point. The tendency to become “fundamentalist” is not just found in religion- but also among scientists. Richard Feynman writes that “It is imperative in science to doubt; it is absolutely necessary, for progress in science, to have uncertainty as a fundamental part of your inner nature. To make progress in understanding, we must remain modest and allow that we do not know. Nothing is certain or proved beyond all doubt. You investigate for curiosity, because it is unknown, not because you know the answer. And as you develop more information in the sciences, it is not that you are finding out the truth, but that you are finding out that this or that is more or less likely.”

  3. Thank you for the reply and Feynman’s wording. It is a lesson of sorts to watch the certainties and uncertainties about the coronavirus swing back and forth as more is learned about it. Hoping for certainties, living with the uncertainties.


  4. Thank you for the reply and for Feynman’s words. Along those lines, it is a lesson of sorts to watch people’s attitudes of certainty and uncertainty play out in regard to the coronavirus as we all learn more–the hopes for certainty, the challenges of uncertainty.


  5. I recently read a meaningful autobiography by Richard Holloway. In it, he reminded that the opposite of faith is not doubt. The opposite of faith is certainty.
