Yes. But the question is: do these things have a truth for our mind?
People talk about God as though they knew what that word ‘God’ means. But God is really just a word, a concept, an idea for people. So it has no truth.
There may be something that the word ‘God’ rather clumsily points to, but that reality is beyond anything that thought can grasp. So to grasp it, our mind must also be beyond thought and concepts.
But our minds are not beyond thought and concepts. In fact, our mind is pretty much made up of our thinking and conceiving. So to face this in ourselves is to face reality. It is to face - as K called it - actualities in the field of reality (‘reality’ meaning in this instance ‘thought’).
But we can drop this narrow and specific way of using the words ‘truth’, ‘reality’ and ‘actuality’ if we have grasped the point. Which is: we mostly live in functions and problems of our own creation, and to deal with this we have to see ourselves factually, as we actually are, and find out if we can go beyond what we are (and if there is, apart from nature, a ‘beyond’ to discover).
