@ineffableG you can extract the pure logic of conditional statements using keyword indicators.

In this example, the keyword indicator is "the only" which introduces a sufficient condition.

The sufficient condition is the left side of the arrow, so this statement would be diagrammed as follows:

PFM ("people for me") ➡️ M ("mad ones")

The contrapositive (reverse and negate) would be:

not M ➡️ not PFM

Hope this helps! For a more in-depth discussion of these concepts, check out our lesson on Sufficient & Necessary.

Sufficient & Necessary is the most commonly tested form of reasoning on the LSAT so it is really important that you know these concepts like the back of your hand.
