When mental construction is underway. It's hard to overstate the efficacy of this way of thinking. "Thought is the bedrock of knowledge." Never give that up or let it be taken from you. Theologies loathe unrestricted thought. It's important to keep in mind that the investigation poses no threat to the truth. If something or someone is challenging your right to ask questions, the problem lies not with you but with them.
