Fallacies: H (Part 2 of 2)

Core idea

The back half of letter H confronts two heavier kinds of fallacy. One is the family of "alternative" medical cults — homeopathy, aromatherapy, floritherapy, naturopathy — that dress up unproven claims in the vocabulary of healing. The other is the set of rumours that have grown around the Holocaust. The topic treats both the same way: ask for the evidence, and weigh it carefully. Belief without proof is the error whether the subject is a flower remedy or a historical atrocity.

Why it matters

This topic shows verification working in opposite directions. With medical cults, the demand for evidence deflates a claim — a homeopathic dilution may not contain a single molecule of the drug. With Holocaust rumours, the same demand defends the historical record: the "soap from bodies" story is shown to be unsupported by shipping records or DNA, while bone-crushing to destroy evidence is shown to be real and documented. Evidence does not take a side; it tells you what actually happened.

Why the myths persist

Scientific-sounding language disguises an empty claim

Homeopathy borrows the grammar of medicine — "potencies", "remedies", "dilutions" — without its substance. Aromatherapy and floritherapy assign moods to flowers from "meaningless aphorisms." The vocabulary does the persuading.

A horror story spreads faster than its refutation

The Nazi "soap from bodies" rumour traces back to First World War propaganda and travelled by word of mouth through the camps. It persisted because it was both horrifying and, in spirit, consistent with real atrocities — even though the specific claim was false.

A familiar phrase is taken literally

"Home, Sweet Home" is assumed British; the words are American and the tune Sicilian. "Husband" is assumed to mean a married man; it originally meant the manager of a household.

Practical application

When a claim invites belief, ask what kind of evidence would settle it:

1. Test the mechanism, not the vocabulary. "Potency" and "remedy" sound medical. Ask what is physically in the bottle — at high homeopathic dilution, often nothing.
2. Apply the standard symmetrically. Demand evidence for the comforting claim and the disturbing one alike. The "soap" rumour fails; documented bone-crushing passes. The method does not pick favourites.
3. Refuse single-cause "explanations" of large events. A broken heart did not cause the Holocaust. Sweeping events have many causes, and a tidy origin story is a warning sign.
4. Check a phrase before reading it literally. "Husband", "Home, Sweet Home", "Hundred Years War" — each says less, or other, than it seems.

Example

A wellness shop sells a "flower essence" promising calm, beside a homeopathic sleep remedy at "30C potency." Apply the test of mechanism. The flower essence is described as "water carrying a flower's vibration" — ask what is dissolved in it, and the honest answer is nothing measurable. The 30C remedy means the original substance was diluted thirty times by a factor of a hundred; the arithmetic says you would need an impossible volume to find one molecule. Neither bottle is fraudulent in a legal sense, and water is harmless. But the claim is empty, and recognising that — without rudeness, just arithmetic — is the topic's whole skill.
