My philosophical problem starts with morality and ends up at the foundations of reason and truth.

If Christianity is true and God put a moral law in our conscience, what actually forces someone, especially an atheist, to follow it? If conscience can be wrong and is shaped by culture, biology and experience, why should it count as an objective guide?

And if I can doubt conscience, then I can also doubt moral intuitions and even the idea of good and evil. That makes me wonder if morality is really objective at all.

Then the same issue appears with reason. Why should I trust it? If reason mainly evolved because it helps us survive, that does not necessarily mean it leads to truth. It might just be useful for getting by, not for seeing reality as it really is.

But when you try to justify reason or truth, you end up using reason itself, which feels circular. Morality seems to have the same problem.

Thomism says reason connects us to an intelligible reality and truth means matching reality. Instrumentalism says we only need useful models, not deep metaphysical truth.

So the question for me is how you can justify reason, truth and morality without going in circles, or infinite explanations, or just saying “it works so it’s fine.”

This has pushed me away from both simple materialism and easy religious answers, and into a more agnostic position, but still open to ideas like consciousness, the soul, and things beyond just the physical world.

Although I may not be able to respond to everyone, I am very grateful.

My philosophical problem begins with morality and ends up reaching the very foundations of reason and truth.

Starting from the hypothesis that Christianity is true, I questioned the idea of ​​natural law: if God wrote a moral law in the human heart and it manifests itself through conscience, what obliges someone, especially an atheist or non-Christian, to follow that conscience? If conscience is fallible, influenced by culture, biology, and external factors, why should I treat it as an objective moral authority? And if I can question conscience itself, then I can also question moral intuitions, the existence of objective good and evil, and even normativity itself.

This led to a deeper problem: if I can question morality, I can also question rationality. Why should I trust reason? What guarantees that it is oriented towards truth and not just evolutionary utility? Even if reason “works,” this may only mean consistent practical adaptation, not real correspondence with the world. This raises the question of whether metaphysical realism or instrumentalism exists: does objective truth and mind-reality correspondence exist, or are there only coherent internal systems that survive because they function?

In exploring this, I realized that any attempt to justify reason, truth, or reality seems to use precisely what it tries to justify, creating an inevitable problem of circularity. Christianity/Thomism responds by saying that human reason participates in an intelligible reality and that truth is a correspondence between mind and being. Anti-realism or instrumentalism, on the other hand, responds that perhaps we only need useful models, without commitment to strong metaphysical truth.

Ultimately, my problem became this:

How to justify rationality, objective truth, and morality without falling into infinite regression, circularity, or mere pragmatic utility?

And this is what led me to distance myself from both simplistic materialism and easy religious certainties, remaining in an agnostic position open to the idea of ​​soul, consciousness, and non-purely material dimensions of reality.

Thank you for all the responses. I may not reply to all of them, but I will read them.

I recently converted to Christianity (I became a Christian 3 years ago). For the past month, I've been experiencing a significant drop in confidence and a loss of faith in Christ. Each passing day I feel more spiritually empty and tired. I ask that you pray for me, and if you'd like, share your testimonies with me; I always enjoy seeing them

I apologize for writing such a poorly written text; I don't feel motivated and I feel tired.
