Single Idea 16255

[filed under theme 2. Reason / B. Laws of Thought / 6. Ockham's Razor ]

Full Idea

The Razor is good when it councils higher credence to explanations which posit a single cause to multiple events that occur in a striking pattern, over explanations involving coincidental multiple causes.

Gist of Idea

The Razor rightly prefers one cause of multiple events to coincidences of causes

A Reaction

This is in the context of Maudlin warning against embracing the Razor too strongly. Presumably inductive success suggests that the world supports this particular use of the Razor.
