Does God exist?

“Yes, after all…
  • Physical reality began to exist

    man with action clipboard beginning the universe

    Several lines of evidence strongly suggest that the whole of physical reality (all contiguous space, time, and matter) truly began to exist, whether it was at the Big Bang or not.

    This page analyzes six evidences.

    The Universe's having a beginning would support God's existence, because if space, time, and matter began to exist, then the required cause of those three things obviously couldn't depend on those three things. (That would require self-causation.) So the cause would need to be spaceless, timeless, and immaterial. Moreover, it would have needed both the ability and disposition to cause space, time, and matter to exist. This sounds very suspiciously like God, and functions as a powerfully fulfilled theistic prediction.1 By contrast, the discovery that the universe began was a uniquely awkward and surprising development for atheist thinkers; it “was not even remotely expected”.2 (In fact, for a while atheists largely hated it and labeled the idea unscientific.)3

      • Quentin Smith (Atheist professor of philosophy at Western Michigan): “The central idea of this cosmology, that the universe exploded into existence in a 'big bang' about 15 billion years ago or so, seemed tailor made to a theistic viewpoint. Big bang cosmology seemed to offer empirical evidence for the religious doctrine of creation ex nihilo.” [“A Big Bang Cosmological Argument For God's Nonexistence” in Faith and Philosophy Vol. 9. No. 2 (1992): 217]

      • Robert Jastrow (Agnostic cosmologist, director of NASA): “…the essential element in the astronomical and biblical accounts of Genesis is the same; ...” [14.] “For the [non-believing] scientist... the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.” [God and the Astronomers, 2nd ed. (W.W. Norton & Company, 1992), 116.]
  • The Universe is fine-tuned to permit life

    symbols of physics constants with checkmarks

    Of all the known ways the Universe's physical laws, constants, and initial conditions could have been, few ways would ever allow any life to exist.1

    This page analyzes three evidences.

    • First, various constants of physics are fine-tuned, like the strength of gravity, the balance of the strong and electromagnetic force, the weak force, and the proton-neutron mass difference, and the cosmological constant. For example, if the last item were off by 1 part in 10^120 (that is one-hundred and twenty zeroes), the Universe would only ever consist of rapidly dissipating hydrogen and helium—no life ever.
    • Second, various initial conditions are fine-tuned, including its initial mass-density, its initial distribution of energy, the Big Bang's “explosion” strength, the character of the density perturbations yielding star formation, and the density-ratio of radiation to normal matter.
    • Third, various laws of physics are fine-tuned, including the notion of gravity itself, and the strong nuclear force itself, as well as the electromagnetic force, Bohr's quantization rule, the Pauli exclusion principle, and more.

    This is an awkward and shocking development for atheist cosmologists2 because it means for them that we got really lucky for no reason. If God exists, however, then the Universe’s ability to permit life is not nearly so surprising or improbable.3 A life-permitting universe is the kind of thing God would plausibly choose to create.4

    But against the truth of fine-tuning, plausibly…

    And against the relevance of fine-tuning, plausibly…

    1. Specialist Luke Barnes recently co-authored A Fortunate Universe (Cambridge University Press, 2016). He also published a review of the scientific literature, 200+ papers, and confesses he can only think of “a handful of physicists that oppose this conclusion, and piles and piles that support it.” See here for non-theist specialists confessing that the fact of fine-tuning is not in dispute.
    2. See confessions from Lemley, Deutsch, Weinberg, Davies, Townes here. One example:

      Philip Ball (Physicist, 10+ years editor for Nature): “Our universe is so unlikely that we must be missing something… the incomprehensibility of our situation even drives Susskind's team to ponder whether an ‘unknown agent intervened in the evolution [of the Universe] for reasons of its own’…” [“Is Physics Watching Over Us?” Nature, Science Update, 2002.]

    3. See comments from Vilenkin, Davies, Dyson, Polkinghorn, Tipler, Hoyle, Penzias, Greenstein here. One example:

      Fred Hoyle (Former atheist “greatly shaken” by fine-tuning; influential astrophysicist): “A common sense interpretation of the facts suggests that a superintellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question.” [“The Universe: Past and Present Reflections” Annual Review of Astronomy and Astrophysics (1982): 20:16.]

    4. Why would God create a life-permitting universe? See the choice arena section.
    5. [Forthcoming]. For now, to see a compelling and novel critique of the multiverse's utility as an explanation for fine-tuning, consider reading Collins's “The Fine-tuning of the Cosmos: A Fresh Look at its Implications”, available online.
    6. The short answer to this is that the fine-tuning argument does not just say something is improbable, it rather says x is improbable on atheism, but not improbable on theism. So the critic's parody formulation acutally is not a parody; truly, the argument cannot be parodies with rocks easily. One could perhaps posit a rock-loving alien or deity, and say the mass presence of rocks is evidence for that deity. They would be right; it would be strong evidence. The problem is that the rock-loving deity is “ad hoc” (contrived) for no independent reason, quite unlike the God hypothesis. Probabilistically, what this means is that, yes, there is evidence, but all the improbability of the hypothesis shifted onto the prior probability of the rock-loving deity itself (like the proverbial ruck in the carpet that just moves when you step on it). Highly implausible ad hoc hypotheses need particularly extraordinary evidence to overcome their initial improbability. The God hypothesis faces no such problem. For details, see red's objection below titled “God is complex (intrinsically improbable).”
  • The Universe is fine-tuned for doing physics & cosmology

    Of all the known ways that a life-permitting universe could have been, few have initial conditions, laws, and physical constants which would ever allow its potential lifeforms to learn about it.

    See this page to see four examples of this

    The discoverability of the universe ends up being evidence for God because (1.) It is a uniquely awkward and shocking development for atheists because it means for them that we got really lucky for no reason. (2.) But on the hypothesis of theism, the Universe’s amenability to being discovered and known is not nearly so surprising. [Such a user-friendly universe is the kind of thing God would plausibly choose to create.] In defense of both of these propositions, see the intro section here.[Note: these three links will lead to some quotes from experts and a paper, but the arguments are not developed on BeliefMap yet.]

  • Cells, brains, eyes “look” intelligently designed

    There is a strand of DNA and bacterial flagellum next to it.

    Features of living organisms resemble the products of an intelligent mind intentionally arranging parts for a purpose.

    This page analyzes one evidence.

    This is relevant because if God did not exist, then the likelihood of this superficial appearance is very low. However, if God does exist, then life's existing and resembling intelligently designed objects is not nearly so unexpected—it was designed.

    Actually it is not relevant. Plausibly…

    • [Life evolved in an unguided way that mimics the pattern of intelligent design].[Forthcoming]
  • We have mostly reliable cognitive faculties

    Two men think with gears turning by their head.

    Our perception, memory, reason and so forth can justify beliefs, and have a propensity to recommend to us true beliefs rather than false ones.1

    See this page for examples regarding the faculty of philosophical intuition (the most controversial): it justifies beliefs like…

    This is relevant because it is awkward and unexplained if atheism is true, whereas if theism is true, it is not nearly so unlikely or unexpected. After all, creating moral agents with generally reliable cognitive faculties able to interact with each other is the kind of thing a good God would plausibly choose to do.

    Actually it's not relevant. Plausibly…

    • Reliable faculties were selected for by an unguided evolutionary process.[Forthcoming]
  • God-belief is instinctive for humans

    stick figure image of michelangelos creation of man

    Humans are innately inclined to believe in God or gods (contra naturalism), instinctively finding it commonsensical or intuitive, even if they and/or their culture ultimately resist it and are “educated” out of it.

    See this page to analyze four evidences.

    By “intuitive” here, we mean that cognitively healthy humans from childhood into adulthood are innately predisposed to think atheism “seems” false or absurd. This is relevant because in the absence of a new belief which undercuts or rebuts it, it is rational to heed the suggestions of our philosophical intuitions. Doing otherwise runs one into severe worldview consequences, where one is suddenly unable to justify one's most basic beliefs.

  • Some actions are objectively morally wrong

    A man pointing gun at another mans head.

    Some actions are morally wrong despite what anybody believes.
    This is relevant because the existence of such specifically personal facts in the world is unlikely if the world is, at bottom, impersonal (e.g. just particles and physics), and yet it is very much the kind of thing we would anticipate if a God exists who grounds the world and who could not fail to have been loving, honest, etc.

  • Some “necessary being” exists

    pythagoras in front of a chalk board triangle

    Some thing exists which is such that it could not have failed to exist; it could not be missing from any truly possible reality.

    See this page to analyze seven evidences.

    That is to say, there is an entity/thing which, by its own nature, could not fail to exist. This is relevant because the entity in question will, by necessity, have a series of properties which strikingly resemble those of God.1

    1. There are several arguments to discuss here, but for a quicker starter consider Joshua Rasmussen’s “Argument from Limits.” He writes, “Just as the bridge of reason took us to a foundation of all things, the Argument from Limits will take us to a foundation of all properties. Reason will be our light. I start with definitions that lay a foundation for clarity:
      D1: A property P is instantiated = P characterizes something. (Example: the property blue characterizes my shirt, and so blue is instantiated.)
      D2: A property P is explicable = There could be—without contra­dicting any principle of reason—an explanation of P’s instantiation that does not appeal to P itself. (Example: a factory could have produced the first blue shirts, which explains how the property being a blue shirt came to characterize anything.)
      D3: A property P is a limit = Necessarily, whatever has P is limited in some positive respect. (Example: being incapable of thinking coherently is a limit.) …
      1. Every limit is explicable. [My insert: “For example, the limited size of the earth has a consistent (and actual) explanation in terms of the forces that produced the earth.“]
      2. The property, having limits, is itself a limit.
      3. Therefore, having limits is explicable. (1, 2)
      4. If having limits is explicable, something could lack limits.
      5. Therefore, something could lack limits. (3, 4)
      6. If something could lack limits, then something must be perfect.
      7. Therefore, something must be perfect (i.e., God). (5, 6) [How Reason Can Lead to God (IVP Academic, 2019), 182-3.]
      Rasmussen dedicates pages to defending these premises, but the reader will have to consult the book. As an additional quick point consider that the Universe (space, time, matter) exists merely contingently, and akin to the causal argument, its explanation by necessity must involve an entity which is able to exist independently of time, space, and matter (i.e., be immaterial, non-spatial, and atemporal). And of course it must have the ability to bring about the Universe. This all sounds very suspiciously like God.
  • Miracles have occurred

    Jesus raised in front of empty tomb

    Genuine supernatural events have occurred within human history, ones which are plausibly imbued with spiritual significance.

    For example,…

    This is relevant because it is highly unlikely that such supernatural events would occur unless God exists.

“No, after all…
  • God is an incoherent notion

    two arrows colliding one with a brain another with a muscle arm

    God's properties, both individually and/or taken together, are incoherent or yield contradictions.

    After all…

    • One or more of God's monadic properties are incoherent (e.g. being all-powerful (able to lift unliftable rocks etc.), all-knowing, all-good, timeless, spaceless, immaterial, free (free will), perfectly rational
    • One or more sets of God's properties are incoherent (e.g. being both timeless and personal, both timeless and a creator, both omniscient and libertarianly free, both omnipotent and omnibenevolent, both all-just and all-loving).

    This relates to the question of God's existence because if God's properties are incoherent or impossible, then God is incoherent or impossible.

    By way of response, however...

    • It is rather bearing the “maximally consistent set of knowledge, power, and benevolence” that must be incoherent.1
    1. God is generally defined as the greatest, most worship-worthy possible being. This is fundamentally what theists have always wanted, insofar as they think humans were designed to recognize God as such. This notion of God in turn is best understood as follows: the being which bears the maximally consistent set of set of knowledge, power, and benevolence (see Yujin Nagasawa, Maximal God (Oxford, 2017).). While the alleged individual incoherences listed above have a complexity of responses and counter-responses, at the end of the day, most any proven incoherence in the concept of omni-properties will simply force the theist into a logically possible analogue nearby, the very analogue that presumably fits the most worship-worthy possible being.
  • God is complex (intrinsically improbable)

    The flying spaghetti monster symbol.

    The idea of a God existing is extravagant and intrinsically improbable; the so-called prior probability of God’s existence—prior to looking at evidence for or against—seems very low. This is relevant because a low prior probability is functionally similar to having evidence against it. More complex and bold hypotheses have more ways/chances of being wrong. We expect them to be wrong in the absence of sufficient evidence.

    But no,

    • The God of bare theism is more simple than a single fundamental particle. God is a unified soul (an unbreakable thing with no parts)1, and its the simplest possible soul: it only has three fundamental properties (those necessary for being a soul), and in their simplest form—without limits.2
    • Reason alone confirms theism (or something close). [Forthcoming]
      • Stewart Goetz: “Thus a table, unlike a soul, is a complex entity or thing in virtue of the fact that it is made up of parts that are themselves substances (substantive parts). Physical scientists inform us that a table is actually a lattice structure of molecules bound together by attractive powers affecting appropriate capacities, and when this lattice structure is broken by a sufficient force, the table breaks. Unlike a table and material objects in general, a soul is not a complex entity because it has no substantive parts. Instead, it is substantively simple in nature. It is a simple thing. While a soul is complex in so far as it has a multiplicity of properties, it is simple in so far as it has no substantive parts. Thus complexity at the property level is compatible with simplicity at the level of thinghood. [“Human Persons are Material and Immaterial (Body and Soul)” in Debating Christian Theism (Oxford, 2013), 262.]
      • Trent Doughtery: “[The Standard Model of Physics] posits 16 fundamental particles that fit into three categories....Some theists think that the simplicity of a theistic universe should be assessed similarly (See Swinburne 2004, chapter 5...) Theism postulates one brute fact and the rest flows from that in conjunction with necessary truths about value. Bare Theism's fact is the existence of a person with two properties -- knowledge and power -- held in the simplest possible way -- zero limitation. The explanation of every contingent truth (other than his own existence, if that is taken to be contingent, an issue too big for the present discussion) is a function of the goodness of the corresponding state of affairs. Since there is no best world, an arbitrary choice must be made as to which initial world segment to actualize among sufficiently good initial world segments (this wordering allows for "...the universe to unfold in way sperhaps unforeseen to God, if it contains beings with free will or if it contains certain kinds of chance processes). If having a good deal of chance in that world is best, then that world will be expected to have a good deal of chance. So if one applies a method of assessing the complexity of the phsical universe to assessing the complexity of the theistic hypothesis, Theism turns out to be a very simple hypothesis indeed. Naturalism lacks this kind of explanatory simplicty and systematicisy. there will be quite a number of brute facts: the existence of contingent being, the existence of a number of laws, the many particular parameters of those laws, and so on. Counting up the number of brute facts in Naturalism by the same method used earlier will be difficult but it seems that inevitably it postulates more than one brute existent with only two properties held in the simplest ways.” [“Reflections on Explanation and Draper's Argument” The Blackwell Companion to Evil (Blackwell, 2014), 85.]
  • Only the natural world of science exists

    ghost being crossed out

    Fundamental reality is mind-less (or mathematically describable). This is relevant because God is essentially a thinking-thing without limits, and God's nature cannot be captured by mathematical equation.

    No, [All Forthcoming]

    • Abstract objects exist (numbers, shapes, propositions, etc.).
    • Mentalia exist (ideas, beliefs, desires, willings, etc.).
    • Moral facts exist (e.g. torturing a child for fun is wrong).
    • Souls exist.
    • An afterlife/heaven exists.
    • The cause of physical/natural reality exists (since matter and natural laws etc. are contingent).
  • God would opt for less suffering than we see

    A woman is worried at the bedside of a man.

    Any good God who exists would've chosen to ensure less (or no) suffering occur.

    This page analyzes two evidences.

    This is relevant because so many today and throughout history have suffered, sometimes even through horrific pain.

  • He'd opt for more to believe, for relationship sake

    lost man with map with god in clouds crossing arms

    Any loving God who exists would've chosen to ensure less (or no) disbelief occur.

    This page analyzes one evidence.

    This is relevant because there are so many today and throughout history who have inculpably remained in non-belief, persons who have obviously not had any God convincingly meet them or otherwise bring them to belief.

  • “God did-it” is not an explanation

    man with thinking bubble of gods hands creating

    Theistic explanation is illegitimate; real potential explanations cannot feature God.

    This page analyzes eight arguments:

    This is relevant because if God or God's activity cannot feature as part of a real explanation, then God cannot be accepted as the explanation for the Universe's existence. Insofar as God is defined as the creator of the universe, this would render theism irrational. (And so, presumably false?)
