Hello Guys,
I would like to suggest my interpretation of Canvasback's mantra "For those who understand, no explanation is needed and for those who do not, none is possible" as "For those who have the capacity to understand, no explanation is needed and for those who do not have the capacity to understand, none is possible" with the green areas being added for clarification purposes.
I would also like to suggest that this saying means (to me anyways) that there are some people who will understand an issue without an explanation while there are some people who will never understand that issue regardless of an explanation. However that does not mean that there are not people who have the capacity to understand the issue with an explanation.
Jerome
