I interpret your questions as follows:

1.) Do there exist true statements?

A statement is true if it claims a matter of fact. Example: The statement ‚Now it rain at Boston‘ is true if and only if now it rains at Boston, otherwise it is false. And it can be simply decided wheter the statement is true.

I know that the last sentence sounds tautological. But it is not tautological, because the sentence discriminates between a statement and a fact. Being true or being false is a property of statements (= propositions), while a fact either is or is not. More about this see Tarski’s definition of truth.

2.) If true statements exists, how can they be obtained?

To obtain a singular statement like ‚Now it rains at Boston‘ one has to look before to the weather report for Boston.

It is much more difficult to obtain a general statement like ‚All numbers decompose into a finite product of prime numbers‘. But mathematics has proved this statement. Hence it is true.

On the other hand, general statements in science cannot be proved, e.g. ‚The sun shines every day‘. Until now the sun has send its light onto earth every day, but one cannot expect that it continues to do so. In fact, the models of star evolution suggest that the sun ends its activity in about 5 billion years.

Science cannot prove its general statements. But science creates rational hypotheses and tries to confirm, or to refute and improve these hypotheses. I consider this a great insight of the philosopher Karl Popper from the 20th century. More on this see Popper on Hume’s problem of induction.

3.) Is there any field of philosophy that obtains true statements? I do not know any field of philosophy that can improve the situation and prove true general statements. The only field with true general statements is mathematics including also mathematical logic.

The last statement is a fundamental philosophical hypothesis. I do not know if it is true.
