What's the point in searching for truth or knowledge? It doesn't seem as though we can know anything for sure or with any type of certainty and even if we were to get knowledge, it's possible that we'll interpret it wrongly. What's the point in asking for evidence in favor of or against a God's existence? It seems as though one could argue both for and against one given the evidence available. IDK what to believe and the search for any type of truth and knowledge seems pointless, idk, I'm rambling.
This feeling you are experiencing is a natural consequence of philosophical reflection upon certain modes of thinking which call into question the certainty of all things. It is not necessarily truth that you cannot find, but rather it is value that those philosophies have failed to uncover. Also, it may be that there are truths that you accepted as valid that, perhaps, you no longer accept as valid. You may also be having trouble with provable/unprovable truths. If you cannot prove that something is true, then how can you accept that it is true? The answer is that there are some truths that you don't have to prove to yourself - they only need to be proven to other people. For example, you know you exist. You don't have to prove to yourself that you exist, because you know it already
without proof. But you might have to prove it to someone else before he will believe that you do, in fact, exist! He can make many clever arguments that you do not exist because his knowledge of you is tertiary. You do not need these proofs for yourself because your knowledge is direct.
So if even if it's fictional, as long as it's comforting or leads to a better life we should believe it? But I want to know truth and have trustworthy knowledge even if it's not comforting but unfortunately absolute truth or trustworthiness doesn't seem to exist.
It seems that you have answered your question: The reason you search for truth is because you want to know the truth. You say it seems not to exist in an absolute sense and that is a lie. There are truths that exist in an absolute sense and there are truths which are not obvious and there are truths that don't seem to exist in an absolute sense. So you will have to qualify your statement according to the question. You should also consider your mode of acquiring knowledge. How exactly are you going about it? And why is the method of acquisition reliable. For example, sitting in a room and thinking about it is one way to acquire knowledge of a certain limited type. You might write a creative work of fiction that way. But if you want to know if it is or is not raining outside, then the best way might be to stand up, walk outside your box, and take a look at the sky.
