SOCRATES: Then once again, these conscious thoughts are produced by reflex action. PLATO: I do not see how I can know I am conscious, how I can feel alive, if this is true, yet I have followed your argument. SOCRATES: But this argument itself shows that your reaction is merely habit, or reflex action, and that no conscious thought is leading you to say you know you are alive. If you stop to consider it, do you really understand what you mean by saying such a sentence? Or does it just come into your mind without your thinking consciously of it? PLATO: Indeed, I am so confused I scarcely know.
