We do not live in a world that mainly suffers bad policies due to lack of ideas about better ones, or lack of elegant explanations supporting good policies, but one that suffers bad policies due to system and meta-system level incentives.
A scientist can be tactful and PC with his mouth, but not his ears or eyes and certainly not his mind. Truth must reign there above all. For your first allegiance is either to Truth or to Ignorance. Worry about offending, and you are choosing Ignorance.
We meet fellow humans throughout our travels,
Become close — friends, dates, lovers.
Always we are distanced again
from death, geography, or meeting others,
Only dialtone on the phone,
cold and empty beneath the covers.
