Where is the man who has been tried and found strong and sound?
Where is the friend of reason and of knowledge?
I see only sceptics and weaklings.
I see only prisoners in the durance of the senses,
And every fool and every spendthrift
Thinks himself as great a master as Aristotle.
Think'st thou that they have written poems?
Call'st thou that a Song?
I call it the cackling of ravens.
The zeal of the prophet must free poesy
From the embrace of wanton youths.
My song I have inscribed on the forehead of Time,
They know and hate it - for it is lofty.

Solomon Ben Judah Gabirol (Died Between 1070-80.)
