We maybe then recognize the genius of Muslim philosophers such as the 12th century philosopher, Avicenna, who had already cited the essence of Cogito argument (centuries before Descartes) only to dismiss it as invalid based on the claim that we can never experience our thoughts separate from our existence, hence in all acts of thinking the existence of self is presumed.
