Crazy or not, the man had hinted at the possibility of an insincerity on his part, which made him restless.
He determined to question him and see if he really would develop a streak of insanity that would justify him in getting rid of him for the night.
"Brother Man," he said, using the term his guest had given him, "do you think I am living to[sic] extravagantly to live as I do ?" "Yes, in these times and after such a sermon." "What would you have me do ?" Philip asked the question half seriously, half amused at himself for asking advice from such a source.
"Do as you preach that others ought to." Again that silence fell over the room.

And again Philip felt the same impression of power in the strange man's words.
The "Brother Man," as he wished to be called, bowed his head between his hands again; and Mrs.Strong whispered to her husband: "Now it is certainly worse than foolish to keep this up any longer.

The man is evidently insane.

We cannot keep him here all night.

He will certainly do something terrible.
