Question

The positivists argue that since it is impossible to conceptualize, for example, God as a concept that can be pointed to, that concept therefore has no meaning. Until now I thought the answer to this was that some concepts are understood through inward self-reflection and not necessarily through external empirical apprehension (which is what allows expression in a non-private language, and think carefully about this).
Today I thought of another direction: even if we indeed cannot conceptualize and reduce God to a definition that can be empirically pointed to, there are still those for whom His existence is intuitively clear (or at any rate, at the very least, the existence of the soul, or the spirit, or the concept of essence). If so, perhaps one could say that maybe intellectual concepts only conceal God and the spirit, and we need to remove them (of course, we will not be able to define Him, but we can indicate with words that they refer to the undefined God)?
And that leads me to another question: what is the role of the intellect? How do we know that everything needs to be conceptualized?
Thank you very much!
