Can Atheism Be Justified?

skeptic's only, justified, athiest

In October, I started conducting interviews in the “free speech zone” at the University of Missouri. I sit at a table with a sign inviting “Skeptics Only” to come and talk about why they are skeptical about God or religion, and I offer them $5 for their time. A line of waiting interviewees often forms next to the table. Some aren’t even interested in the $5! Some sound justified in their views, and some struggle to articulate the reasons for their skepticism.

Ironically, an atheist friend inspired me to try this. Anthony Magnabosco, a nationally-known practitioner of “Street Epistemology,” runs a YouTube channel with 28,000 followers. He expertly engages in Socratic conversation with people, encouraging them to re-examine the reasons for their most deeply-held beliefs. While I disagree with him about God, I applaud how he models friendly conversation about religion and other touchy subjects.

Pleasant Surprises

believe, belief, think, rationalThe biggest surprise has been people’s candor and willingness to have their story filmed and put on YouTube. I was also pleasantly surprised at the thoughtfulness and depth I heard in many of their responses. Some point to Christians behaving badly as evidence against the faith. Some bring up perceived conflicts between science and faith. Others suggest that a loving God would not allow good people to suffer. These can serve as justifications for atheism.

Some atheists and skeptics, in an effort to gain an edge in the debate about God, will insist that they don’t need to offer support for their view. But nearly all the people I’ve interviewed can offer coherent reasons for their disbelief. I think this is how any rational person ought to respond. Whatever your position is on God, you ought to have a rationally justified basis for that position. You ought to have reasons for your view. Otherwise, it’s no different than blind faith.

A Real-life Example

In the video below, Lacey raises several legitimate reasons for her skepticism.

  • Religion often seems to conflict with science.
  • Christians fail to live up to the ethic of Jesus.
  • Good people suffer for no apparent reason.

Based on her experience and reasoning, she seems quite justified in her rejection of the Christian faith. Her “total evidence” can be construed to point in the opposite direction. But she also seems open to acquiring new evidence and re-thinking her conclusions. This openness further demonstrates her rationality and intellectual virtue.

resurrection, justifiedI probed for further thoughts on a few points she made. For example, if we take bad Christians as evidence against Christianity, shouldn’t we also take good Christians as evidence in its favor? And if we reject the resurrection account, then what alternative explanation do we have for the data (e.g., empty tomb, resurrection appearances, changed lives, etc.)?


I think, given a certain set of total evidence, atheism can be rationally justified. We all possess a different set of total evidence, which makes it difficult to compare our conclusions. What is rational for me may not be rational for you. But openness to hearing one another can help improve our set of total evidence, which may mean revising our beliefs. Do you agree?
