Being reasonable depends on your ability to reason, reason depends on an ability for creative perspective taking with empathy, thus as our shallow ego-driven society craves followers instead of developing philosophers - we all fail to win.
If you want a reasonable world, you must develop and hone the ability to reason. If you want a world of love, you must develop and hone the ability to love. If you want a reasonable world with love, do both. Any questions? Would you listen to the answers reasonably? Would you consider the answers with a loving perspective? Because trying to reason with unreasonable minds is as fruitful as trying to love unloving hearts. Is it too obvious to say that you reap what you sow? Sow what? So what? Are you about to tune out again or tune in?
Reasonable is as reasonable does - actions speak louder than words; I'll read your deeds, I'll hear your actions, then I'll see the real you and if indeed you are reasonable at all.
Reason, re-son, re-sun - are we able to see the light of the son?
