Trying to use logic to create qualifiers for friendship is a slippery slope. Love is not logical, that's not it's nature
I try to not have an extravagant view of logic beyond it being a heuristic approach to get from cause to effect.
In other words, if your actions (as a friend) do not match your avowal of friendship up to some minimum standard....the effect is to nullify the friendship.
What compromise is there between a glass of water and a drop of poison?
I find that those who strive for intellectual honesty seek clarification while those who tend to want to muddy up things
with slippery slopes and exceptions hinder clarity, however unwittingly in motive.
Avoiding absolutes is a great place to start, however.
What purpose does FAITH serve if not to replace missing elements, namely, facts and proof?
Connecting the dots implies a space between the dots where information is missing. Faith is that pencil line that gets us "there".
Love is an appraisal in which we place maximum value on the object of our appraisal. It becomes a transaction demonstrating the magnitude of the appraisal because we trade our time, money, energy and thoughts in much the same way as any other transaction. The more we "pay" the greater the "value" to the one paying.
All the above in order to say, reality is quantifiable in objective terms while imaginary concepts remain subjective and unprovable no matter how much emotion we attach because we want to value something numinous or transcendent.
