I gave much of my life to two ideas: First, the cumulative effect of loyalty is to keep people in their place, so the more friendships we maintain the more our mind is full of 'us verses them' to the point that 'right versus wrong' can be hard to recognize. The opportunity cost of the pecking order is beyond imagination.
Second, definability corresponds to decidability. Semi-decidable concepts form a boundary on deductive systems. Rules that use such a concept cannot embody all of the concept and cannot conflict with other rules. Such axioms are the semantic equivalent to the difference between first order logic and second order logic (see completeness). Thereby, we have a better explanation of Godel's incompleteness theorems (which are not theorems BTW) along with their correspondence to (weak) Turing completeness.
math, philosophy of math, computer science:
A lot of mathematics is about proving theorems, but when a statement cannot be proven true or false we have the opportunity to better understand mathematics. I feel that we, unfortunately, do not take advantage of those opportunities. As our understanding of mathematics grows, we may ask more questions that land on the boundary of what we can know. I expect that it will only become more important to grapple with logical independence.
