The text says: "Some men seem to be obsequious in association with others and in interchange of words and deeds. They praise everything for the sake of pleasantness, and never contradict anyone, being of the opinion that unpleasantness ought to be avoided."
My question lies here in the commentary: "He says that in human conversation and generally in all human companionships some seem to be obsequious, as it were straining to please men. They praise everything that others say and do for the purpose of making themselves aggreeable."
Is the word "strain" here an intransitive verb? According to MW, then the meaning would be "3. to make a great difficulty or resistance" so as to stress the extent that it appears to be very difficult to please men therefore some seem to be obsequious.
Did I understand it correctly? Thanks.
