Ten Things Natural Science Cannot Do

One of the most insidious falsehoods perpetuated in contemporary culture is the idea that natural science is final arbiter of truth and the ultimate hope of human salvation. Below I have listed ten things natural science cannot do. This list demonstrates that human beings cannot live a human life by natural science alone. It’s far too narrow, and it aims way too low. We need access to a truth science cannot supply and contact with a reality science cannot touch.

  1. Natural Science cannot answer a single important question—not even one. Science cannot establish the worthiness of anything it does.
  1. Natural Science cannot establish the validity of its methods or the truth of its theories. Science cannot demonstrate that it is doing anything more than organizing our empirical experience into meaningful patterns.
  1. Natural Science cannot prove the rightness or goodness or beauty of its activities.
  1. Natural Science cannot give you a reason to become a scientist or even to live another day.
  1. Natural Science cannot make a single moral, aesthetic, metaphysical or theological statement. Science is limited to describing, explaining and predicting the empirical structure and behavior of things in terms of physical causes, spatial and temporal relations, quantitative relations, organic functions, etc.
  1. Natural Science possesses no competence speak about existential meaning or purpose.
  1. Natural Science has nothing to say about to you as a person. It cannot tell you who you are, why you are here or what you are supposed to do.
  1. Natural Science cannot guide itself toward ends. Science has no mind or heart or soul; it cannot love or hate or feel. It cannot do anything or feel anything or think anything. It cannot read or write or speak. Science exists solely in the minds of scientists and is a wholly human enterprise subject to the same error and sin as are such other human enterprises as politics and economics. If human reason is limited, science is correspondingly limited. If human goodness is limited, science is limited accordingly.
  1. Natural Science cannot give you hope for the future or reason to love others or others reason to love you.
  1. Natural Science cannot forgive your sins, raise you from the dead or give you eternal life. It cannot tell you God loves you. It cannot give you the power to live a good life. It cannot comfort you at the graveside of your loved one or in your own dying hours.

Creation or Big Bang Evolution?

The effectiveness of contemporary objections to Christian belief derived from the discoveries of natural science depends on misunderstanding or distorting science’s domain, scope and competence. In the last two weeks I’ve worked on clarifying these misunderstandings and distortions. As I said last week, modern science attempts to explain data derived through the five senses by creating theories that predict future empirical states that, if they occur, support the explanatory theory. I realize this oversimplifies things a bit, because for different natural sciences—physics, chemistry, biology—the particular intermediate theoretical languages differ.

Physics and chemistry are highly mathematical, whereas biology, while still mathematical, adds other types of relationships among the things it studies, specifically function. The category of function is needed in biology because this science deals with organisms, which are obviously organic wholes in which molecules, cells and organs contribute their part to the proper functioning of the organism. Hence biological explanation involves showing how each part functions in relation to the higher systems and finally to the total organism. However, in all natural sciences a transition from one state of the empirical world is related intelligently to a future (or past) state of that same empirical world by means of an explanatory theory that explains why the transition took place as it did.

In modern natural science, all the explanatory theories used to explain transitions from one empirical state to another appeal to the physical properties of the prior state to explain the change in form that is manifested in the subsequent state. There is nothing objectionable in this restriction. This is what empirical science does. But when thinkers claim that everything real and every event that occurs must be explained by the physical properties of the things involved, that empirical method is the only way to truth, and that all truth can be stated in empirical terms, they are grossly distorting science’s domain, scope and competence. Given this false assumption about science, objections to Christian belief based on particular scientific discoveries (Big Bang, biological evolution) are redundant; for the objectors have already ruled out belief in divine action in their presuppositions. But if you do not accept the assumption that everything real and active is physical and empirical, you need not accept the conclusion that the big bang and biological evolution compete with belief in God and God’s all-pervasive action in the world.

The Big Bang

The Big Bang theory relates the present empirical state of the universe to earlier states and ultimately to the earliest state to which accepted physical laws apply (between 15 and 20 billion years ago). The theory accounts for certain empirical observations of the present universe: the universe appears to be expanding; the further away a galaxy is, the faster it is moving away from us; the uniform (or near uniform) background radiation in every direction; and much more. These observations are combined with the theory of relativity and quantum physics to conclude that at some finite time in the past the universe was so compact that everything in it was in one place (the singularity), that space and time had not yet emerged, and that the temperature was virtually infinite.

Let’s not get hung up in a discussion of the Big Bang’s scientific truth right now. Instead let’s remind ourselves that even if its empirical claims are true, it cannot rightly claim to be the whole truth. The Big Bang is not a theory of everything. It does not cover the same ground as the Christian doctrine of creation. It does not even speak the same language. It is a theoretical account of the development of the present cosmos from a previous state. It begins with an already existing universe, and it describes and accounts for the changes from earlier to later stages of the cosmos with theoretical articulations of the physical properties of the elements within the observable world. On a theoretical level it speaks the language of mathematics. That is the secret of its explanatory power but also of its poverty. It cannot speak or understand another language. There is absolutely nothing in the Big Bang theory that explains away or rules out the action of God in calling the universe into existence, giving it the form it has, guiding it to the place it is, or leading it on to the destination God has in mind. The Big Bang cannot explain or rule out the reality of the qualities we experience or the mind we possess or the freedom we exercise. It cannot explain or rule out meaning, truth, beauty or moral law. It cannot tell you who you are or why you are here. If you have other grounds on which to believe in the reality of God, our minds, the intelligibility of nature, the moral law, human freedom and creativity, and the meaning of cosmic history, the Big Bang theory of cosmological development poses no rational threat at all to those beliefs. It’s simply a non sequitur, irrelevant, beside the point. As a cosmological theory, it’s elegant. As an objection to Christian belief, it’s lame.
