Line of Reasoning

The difference between a list and an argument

A line of reasoning is a sequence in which each paragraph depends on the one before it. A list is a set of reasons in no necessary order.

The reorder test: swap any two body paragraphs. If the essay reads exactly as well, you have a list.

Common shapes that do progress

• Concession then pivot — grant what the other side gets right, then show what it does not reach.
• Narrowing — from the general claim to the specific case where it bites hardest.
• Causal chain — A leads to B leads to C, where the surprise is at C.
• Reframing — argue that the question itself is the wrong question, then supply the right one.

Transitions carry the logic

Weak transitions name position: first, second, another reason. Strong transitions name relationship: but this holds only if..., which is precisely why..., the same evidence, read differently, suggests...

If your transitions are all positional, that is itself evidence you are listing.

Reasoning flaws to recognise

• Hasty generalisation — a conclusion from too few cases.
• False dilemma — only two options presented when more exist.
• Post hoc — treating sequence as cause.
• Straw man — refuting a weakened version of the opponent.
• Circular reasoning — the conclusion restated as the premise.
