I would say. The Buddha just didn’t have that much to say about the epistemological and metaphysical questions that preoccupy systematic philosophers in all ages. The Buddha was interested in a limited range of phenomena open to the inward investigation and mindful attention of the suffering individual, and directly related to liberation from that suffering. The teaching is about how we make conscious contact with the sensual forms that pass before our outer and inner senses, and then conceptualize those forms, feel and respond emotionally to them, thirst after them, cling to them, build them into our anxious and fearful sense of self and possession, and as result shroud ourselves in the samsaric stream of birth and death, and become part of that stream of misery.
