Assuming knowledge is gathered and presented without an implicit bias or agenda, which is nearly impossible, the choice of the starting point on most things in life can radically alter the knowledge.
For example, a logger or poacher will possess a very different knowledge of a forest from a tribal native; even if the tools used to acquire their knowledge are the same five senses. Science, logic and academia present very useful view points, I have no quarrel with them, but they are not the only point of view, and in my experience aren't yet the most useful for inquiring into subtle things with life, like the ways of the spirit or faith which are often full of paradoxes and non-dual expression. Like many jokes this one vastly exaggerates the situation, but there was a drunk who lost his keys in a dark alley; he was later found looking for it on the main street where there was light. Some times to get at the truth we need to get on our hands and knees and grope around and put in a lot more effort than we wish. I am definitely not helping with your immediate quest with all this neck beard talk, but I am not sure I'd do a better job than Google or Amazon in finding your book. This is a more productive discussion in my world view :)
