Everything begins with an assumption. What do you assume to be fact?
You will need to identify within yourself, Scientific Assumptions, Philosophical Assumptions,
Religious Assumptions, Legal Assumptions, Historical Assumptions and so forth and so on.
What things do you refer to generally, as False?
When you can identify What---You---Know, then you have a foundation.
You must then know these things in the English Language.
Let's look at some basic examples of basic subjects in life, that you should be able to decide.
(a) Is there a God?
(b) Should we accept what other people say without question?
(c) Is the Universe Finite or Infinite?
(d) Do human beings have rights? What rights to human beings have?
(e) Is there such a thing as a Higher Consciousness?
(f) Is Matter, Energy, Space, and Time all that exists?
(g) Is Love the answer to anything?
(h) Does human life have value?
When you can identity basic assumptions as to what is true and what is false in human experience, you will have the ability to write in any language about general subjects.
What I can tell you is that if our studies in a language are only preparing us to talk about
household things, tourist travel, or the equivalent of
What----Restaurants---Or---Movies---We---Like, we will not have much facility with written language.
Here is a good starting point for you. There are about four key words in English which have many synonyms. They are SEE, SHOW, MAKE, CREATE. You should become familiar with these four words and their use in simple sentences at first. Let me give you some examples that you can begin working with to become a good communicator in written English. I will also use some of their synonyms.
