To be a vegetarian does not suffice. We must not cease from mental fight
before all humanity has committed to synthetic food.
Until he extends his circle of compassion to include salad greens,
man will not himself find peace.
clue:
I will not cease from mental fight
Nor shall my sword sleep in my hand
Till we have built Jerusalem
In England’s green and pleasant land.
— William Blake
“Until he extends his circle of compassion to include all living things, man
will not himself find peace.” — Albert Schweitzer
