Jane: What is red?
John: It is a concept.
Jane: What are concepts?
John: They are the constituents of complete thoughts.
Jane: If concepts are constituents of complete thoughts, where do they exist?
John: They exist in our minds, of cause.
Jane: Are there eternal concepts?
John: What do you mean by eternal concepts?
Jane: I mean concepts that are independent of our minds for their existence.
John: Do you mean concepts that are true even if there was no contingent rational being?
Jane: Yes, John. Example could you say that 2 = 2 or the law of non-contradiction is an eternal concept?
John: Yes, I believe so.
Jane: So, if there are eternal concepts, would you agree that there is at least one eternal mind?
Jane: If there exist eternal concepts, and concepts are the constituents of complete thoughts, are we not rational to believe that there is transcendental mind?
John: I am persuaded to think it is rational, Jane.
Jane: Well John, monotheists would call this transcendental or eternal mind, “God”.
Those in doubt about any of Jane’s assumptions (e.g. conceptual realism & Platonism) may take her main conclusion conditionally. Is Jane’s argument for existence of God as an eternal mind persuasive? It depends on whether or not you share her assumptions. For those who do not, it is not a persuasive case. Why present such a dialogue then if it persuades only those who share Jane’s assumptions. My aim is not so much to persuade all, mostly atheists, to reconsider their position on the existence of transcendental mind. I do not believe in transcendental mind because of such arguments. My aim is to show that belief in God, a transcendental mind, can be rationally justified. Monotheists can (and do) have rational reasons to believe in such a being.
