Although it is important to understand that moment of loss (the loss of the grasp of your thought)—although this is important for the purpose of understanding the question, one’s difficulty, and important for method and for understanding the activity of philosophy—this drowning of oneself in confusion can become addictive. It can become a temptation, a vice.
One might even say: it is only safe to lose oneself like that when you are trying to think of God. Or perhaps: when one is losing oneself like that, this is one speaking (or trying to) about God. Even the most secular philosopher is thus a philosopher of religion. Philosophy is philosophy of religion. I mean, that philosophy is philosophy of religion is something that takes care of itself.
