Of course it is not necessarily the business of a novelist, or a satirist, to make constructive suggestions, but the point is that Dickens' attitude is at bottom not even destructive. Hence it is a good idea to avoid ending a paragraph with a quotation.
But if your analysis is lengthy, you may want to break it into several paragraphs, beginning afresh after the quotation.
If your quotation is longer than four lines, do not place it in quotation marks.
Instead, set it off as a block quotation: The truth is that Dickens' criticism of society is almost exclusively moral.
If an argument or a factual account from one of your sources is particularly relevant to your paper but does not deserve to be quoted verbatim, consider: Note that most scientific writing relies on summary rather than quotation.
The same is true of writing in those social sciences --such as experimental psychology -- that rely on controlled studies and emphasize quantifiable results.
Moreover, the technique of weaving can help you to produce a tighter argument.
The following condenses twelve lines from Arendt's essay to fewer than two: What Arendt refers to as the "well-known realities of power politics" began to lose their moral legitimacy when the First World War unleashed "the horribly destructive" forces of warfare "under conditions of modern technology" (13).
The following offers just one way of introducing the above quotation: , "we must turn to Roman antiquity to find the first justification of war, together with the first notion that there are just and unjust wars" (12).
Since the quotation is relatively short, the brief introduction works.
