Suffer not the fashonable Fools

Rouze up O Young Men of the New Age! set your foreheads against the ignorant Hirelings! For we have Hirelings in the Camp, the Court, & the University: who would if they could, for ever depress Mental & prolong Corporeal War. Painters! on you I call! Sculptors! Architects! Suffer not the fashonable Fools to depress your powers by the prices they pretend to give for contemptible works or the expensive advertizing boasts that they make of such works; believe Christ & his Apostles that there is a Class of Men whose whole delight is in Destroying. We do not want either Greek or Roman models if we are but just & true to our own imaginations, those Worlds of Eternity in which we shall live forever; in Jesus our Lord.

And did those feet in ancient time,
Walk upon Englands mountains green:
And was the holy Lamb of God,
On Englands pleasant pastures seen!
And did the Countenance Divine,
Shine forth upon our clouded hills?
And was Jerusalem builded here,
Among these dark Satanic Mills?
Bring me my Bow of burning gold;
Bring me my Arrows of desire:
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 Englands green & pleasant Land

 -- William Blake, Preface to Milton (1810)
