Sentence:  When a sincere man marries a wife, he has one or two courses open to him, which he can pursue with that wife. He can propose to himself to be (a) the <WSD>lord and master</WSD> who is honored and obeyed, (b) the perfect lover, (c) the true friend and companion. Of these (a) is now rather out of date. The <WSD>lord and master</WSD> has been proved, by most women quite satisfactorily, to be no more than a grown-up child, and his arrogance is to be tolerated just as a little boy's arrogance is tolerated, because it is rather amusing, and up to a certain point becoming. 
Meaning of the word marked with <WSD> tags:  A husband, especially one who is domineering.
