Political language and with variations this is true of all political parties, from Conservatives to Anarchists is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind.One cannot change this all in a moment, but one can at least change one's own habits, and from time to time one can even, if one jeers loudly enough, send some worn-out and useless phrase some jackboot, Achilles' heel, hotbed, melting pot, acid test, veritable inferno, or other lump of verbal refuse into the dustbin, where it belongs.Having read your essay, we should understand this main thought with fresh and deeper understanding, and your conclusion wants to reflect what we have learned.
The conclusion is the last thing that your reader will see, so it should be memorable.
If you simplify your English, you are freed from the worst follies of orthodoxy.
You cannot speak any of the necessary dialects, and when you make a stupid remark its stupidity will be obvious, even to yourself.
The last thing we want in our conclusion is an excuse for our readers' minds wandering off into some new field.
Allowing a peer editor or friend to reread our essay before we hand it in is one way to check this impulse before it ruins our good intentions and hard work.
