Urthona is variously described as the imagination, the unconscious, or the intuition; but always Urthona is connected with man's ability to perceive the spiritual. Damon states that: "In the Trinity, Urthona corresponds to the Holy Ghost." Los and Enitharmon are manifestations of Urthona who are active in the lower worlds.
At times when Los is split from Enitharmon he is referred to as the Spectre of Urthona. In this passage the colloquy is between Los and his own spectre, not the Spectre of Urthona.
We read that Los embraced his Spectre and accepted him as a brother or another self. The Spectre, however, choose not to be one of many selves or in any way subservient to Los as an expression of Urthona.
We think of much of the functioning of the human psyche taking place through the Ego which allocates activities to each division. The Ego identifies with the reasoning mind and assigns a large proportion of activity to reason. Los needs his reasoning mind which is represented by his Spectre, but when he embraces his reasoning mind, it wants to assume control. Additional processes will ensue before the two come together.
