what does the poet Wilfred Owen mean by the phrase"Wildest beauty in the world" in his "Strange Meeting"?

The "hunting wild after the wildest beauty in the world" corresponds to Owen's high-sounding quest for beauty and truth which in former days he believed he had inherited from Keats and Shelley but which was really a substitute for thought and experiences he had not yet undergone. A continuation along these lines might have achieved something but not what was to be the core of his short life's work: The pity of war, the pity distilled.
