I love this table for it's relatability. However, I felt lost in the text putting the table into context. Specifically the sentence,
"But when the rest of us talk about rationality we still mostly talk in abstracts.".
What is really actually meant by this? Both, what is meant by "rationality" in general and what examples should be thought of for "abstractions", are lost on me. Does it apply to everyday talk with friends, what are abstractions there? Does it apply to truth seeking communities like this forum, and what abstractions are used here? Does it appply to scientific communication, other than when using formulas instead of text to carry the concept to the audience?
