instead of arguing a proposition is true or false, this argument concludes that it is impossible to rationally accept naturalism. here are the reasons for this:
1. P1 if naturalism is true, then there is nothing beyond our physical selves.
2. P2 evolution is a process that operates with the goal of survivability.
3. C1 our cognitive functions have come into being by the process of evolution- from P1&P2
4. C2 all our cognitive functions came about for the purpose of survivability which is not necessarily hinged on determining the truth- from P2&C1.
5. C3 we have no way to know if our reasoning leads us to truth in any proposition including the proposition of naturalism itself. any and all propositions based on our cognitive faculties (which are all of them) then are just as likely to be correct as they are to be incorrect- from P2&C2.
conclusion: it is impossible to rationally believe in naturalism. the very concept of naturalism entails the possibility of our cognitive faculties being unable to reason truth, which includes all truths including naturalism itself. it's self defeating. and before someone asks why this doesn't apply to religion like Christianity, the answer is P1 isn't a claim of Christianity and in fact is inconsistent with Christianity. if P1 is false, then C1 doesn't logically follow. a Christian can simply claim their cognitive faculties are indicators of truth by the intent of our designer.
extra notes- before i'm misunderstood I want to make it clear, this argument is not formulated to prove naturalism is false. I hope to see no one who interprets it that way. it is only meant to show how it is impossible to rationally believe it for the reasons in the argument. it shows that presupposing naturalism is true entails the best probability for all our beliefs to be correct is 50/50 since we can't know if our cognitive faculties are in fact indicators of truth. that is it.
Ahh this is why we employ the scientific method, because that allows us to know if our reasoning is accurate.
Quote: I. The scientific method has four steps
1. Observation and description of a phenomenon or group of phenomena.
2. Formulation of an hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation.
3. Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations.
4. Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.
If the experiments bear out the hypothesis it may come to be regarded as a theory or law of nature (more on the concepts of hypothesis, model, theory and law below). If the experiments do not bear out the hypothesis, it must be rejected or modified. What is key in the description of the scientific method just given is the predictive power (the ability to get more out of the theory than you put in; see Barrow, 1991) of the hypothesis or theory, as tested by experiment. It is often said in science that theories can never be proved, only disproved. There is always the possibility that a new observation or a new experiment will conflict with a long-standing theory
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
