     As a political system democracy seems to me extraordinarily foolish, . My servant is, so far as I am concerned, welcome to as many votes as he can get. I do not suppose that it matters much in reality whether laws are made by dukes or cornerboys, but I like, as far as possible, to associate with gentlemen in private life.

     Whether modern, industrial man is less or more warlike than his hunter-gatherer ancestors is impossible to determine. The machine gun is so much more lethal than the bow and arrow that comparisons are meaningless. One thing that is true, though, is that murder rates have fallen over the centuries, as policing has spread and the routine carrying of weapons has diminished.

2. Without a correlative, introduces a simple indirect question.

   Whether we'll be on time I'm unsure.

   Do you know whether he's coming?

3. Introduces a disjunctive adverbial clause qualifying the main clause (with correlative or).

   He's coming, whether you like it or not.

   I'll enjoy playing with my friends again, whether we win or lose.

   Whether or not you're successful, you can be sure you did your best.

• Traditional grammar classifies senses 2 and 3 as whether heading a noun clause, but classifies sense 4 as whether heading an adverbial clause.
• There is some overlap in usage between senses 2 and 3, in that a yes-or-no interrogative content clause can list the two possibilities explicitly in a number of ways:

Do you know whether he’s coming or staying?

Do you know whether he’s coming or not?

Do you know whether or not he’s coming?

Further, in the first two of these examples, the “or staying” and “or not” may be added as an afterthought (sometimes indicated in writing with a comma before), such that the whether may be uttered in sense 3 and then amended to sense 2.

• The or not can be placed after whether or after the verb, although in senses 2 and 3, or not is not required.
• Sense 4 does not have a counterpart that introduces only a single possibility and thus requires or not if no other possibilities are presented. For example,

“He’s coming, whether you like it” is ungrammatical. Grammatical versions are “He’s coming, whether you like it or not” or “He’s coming, whether you like it or dislike it”.

• The main verb in adverbial clauses with whether is sometimes in the subjunctive mood, especially if the verb is be:

I shall be glad to play any instrument, whether it be a violin or a trumpet.

• either
• neither
• whethersoever
