Bring me my spear! O clouds, unfold!
Bring me my chariot of fire!
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.
The "mental fight" we are perpetually engaged in does not happen outside us but also within us. Somewhere we need to introspect and honestly address our own position in the critique we make of the social order as a whole.
