Hopping in on this thread to request a copy of the checklist if it's still available! Thanks in advance and happy studying everyone.

I’m also in!

Visualizing these arguments is helping me learn them:

The Conditional Argument:

Imagine a conveyor belt (→) where if A items come in, B items come out. If you put something on the conveyor belt, you will get the corresponding outcome.

The Contrapositive Argument:

Visualize a seesaw with A on one end and B on the other. If B goes down, then A must go up to balance it out.

Conditional Chaining:

Picture a train moving from A to B to C. If the train goes from A to B and then from B to C, logically, it's like it directly went from A to C.

Some Before All:

Imagine a group of people entering a room. If some people (A) are in a room with all of B and some of B are in a room with all of C, then logically, some of A must also be in the room with all of C.

Most Before All:

Think of a river flowing from A to B to C. If most of the water flows from A to B and then from B to C, it means that there's a significant portion of the water from A that ends up in C.

Two Mosts:

Visualize two buckets, one labeled B and the other labeled C. If most of the items in bucket A can fill both buckets B and C, then logically, there must be some overlap between the contents of buckets B and C.

I feel like #5 is essential to understanding this lesson. I don't totally agree with the argument that the symbolism of "21+" is superior but I can see where 7sage is coming from.
