Phronema

In the context of software engineering mentorship, phronema (borrowed from Eastern Orthodox theology) refers to the living, internalized mind or judgment of a discipline. It is the deep understanding that allows an engineer to know the right move in a situation no rule covers.

Mentorship is the transmission of phronema.

When senior engineers rely on thought-terminating clichés (like YAGNI or Premature Optimization), they withhold this living understanding and hand over a dead rule instead. This damages the mentorship relationship and teaches juniors not to propose ideas.
