The intellect should be the servant of the heart, but just because the heart should be the master dose not mean the intellect should not be used. A courageous heart requires an intellect capable of fighting its master’s battles.
The heart caves truth. The heart craves justice. The heart craves compassion and aid for the victims of cruelty and oppression. In a world such as ours, the heart needs a warrior intellect strong enough to fight the greedy oligarchs, the powerful forces of the secret intelligence services, the warmongers, propagandists and brutal cops, etc.
