Confused about Philosophy.

Is there such thing as a perfect stance? For example there is scientific naturalism, Cartesian dualism, determinism, etc. Which one is logically perfect? Also, when people say they're an Aristotelian or Kantian does that mean they only think that they're philosopher is the only one who got it right? I'm so confused on how big philosophy is....

Philosophy IS huge! You are not alone in being overwhelmed by the sheer amount of work in the field.

To start, your question about if any philosophical arguments or positions are “logically perfect”. This is a hugely contested question of course, but there are two measures we use about this. In logic we talk about two concepts in this way: validity and soundness.

An argument is valid if the propositions taken together *would imply* the conclusion they reach *if they were true*.  We can analyze an argument as valid or invalid based on hypothetical truth. 

An argument is sound if it is valid and true at the same time. Usually we see Validity to be the realm of logic and Soundness to be what philosophers argue about— truth of propositions.

Many arguments are valid. Which means they are logically well made, but the same can’t be said about their arguments being sound. 

Furthermore, when an individual is a Kantian or Aristotelean what it means is that they are heavily influenced and defending a version of some philosophical argument or paradigm set forth by that philosopher or that has its origin in that philosopher. They are not committed to the idea that Kant or Aristotle was never wrong, or that other philosophers have all been wrong.
