I propose the hermeneutic meme, an individual unit of understanding. Wisdom, in its abstract forme and ambiguous state, acts as a variable list of ingredients, the gradients of value move towards the homeostasis of the ideal.
This reminds me of the PFC origins story from Robert Sapolsky. The power of 'maybe' biases human kind towards the possible, however improbable. This is the p.(x), where hope has nothing to do with it and probabilities are all that remain!
