Kornfield is described as conveying a very similar approach to the psychology of religion as had Abraham Maslow, that the commonality of religious experience was the significant thing (not the specific explanation of it by the experiencer) and that the sign of it being psychologically healthy was whether an experience allowed for a deeper integration of the self alongside societal beneficence, as opposed to a separating or isolating experience.
Thanissaro asks if using this sort of assumption, alongside a few other Romantic assumptions which form the basis of the talk, does justice to the Dhamma. One example used is the idea of interconnectedness, seen as a good thing in Romanticism but seen as simply one among many contemporary views which the Buddha suggests has nothing to do with the problem of dukkha. "Truths that aren't useful", as it were. It's later specified that any interconnectedness which can be found in the Dhamma has to do with paticcasamuppada, which is the process of dukkha - not sukha, which is basically the Romantic claim.
Another example is that, to a Romantic, this process of improvement is infinite as the path is
the goal, whereas to a Buddhist there is a definite goal - nibbana.
