  Passages such as these surely attest to the great importance the Buddha placed on sharing his insights to help others overcome suffering. But this is consistent with the belief that philosophical rationality may be used to answer questions that lack evident connection with pressing practical concerns. And on at least one occasion the Buddha does just this. Pressed to give his answers to the questions about the arhat and the like, the Buddha first rejects all the possibilities of the tetralemma, and defends his refusal on the grounds that such theories are not conducive to liberation from saṃsāra. But when his questioner shows signs of thereby losing confidence in the value of the Buddha’s teachings about the path to the cessation of suffering, the Buddha responds with the example of a fire that goes out after exhausting its fuel. If one were asked where this fire has gone, the Buddha points out, one could consistently deny that it has gone to the north, to the south, or in any other direction. This is so for the simple reason that the questions ‘Has it gone to the north?’, ‘Has it gone to the south?’, etc., all share the false presupposition that the fire continues to exist. Likewise the questions about the arhat and the like all share the false presupposition that there is such a thing as a person who might either continue to exist after death, cease to exist at death, etc. (Anālayo 2018, 41) The difficulty with these questions is not that they try to extend philosophical rationality beyond its legitimate domain, as the handmaiden of soteriologically useful practice. It is rather that they rest on a false presupposition—something that is disclosed through the employment of philosophical rationality.
