Ibn'Arabi's way of thinking from the Futuhat

Is Ibn'Arabî a philosopher? Between Al Gazalî and Averroes, he is the mystic philosopher the most close to Islam, says the author. Ibn'Arabî, who reached the highest degrees of spiritual realization, acquired his knowledge by inspiration. Non rational, it comes from the heart. God is the great inspiring; Ibn'Arabî the great servant. Great erudite, this one integrated in his work many philosophic and theological references.
What is the relation between Sufism and the philosopher himself? How does Ibn'Arabî integrate philosophy to his divine experience through his way of thinking?   What is his theory of expression?
