Whatever is happening to Caleb, it’s as old as war itself.

-This is an analogy claim because it’s comparing what’s happening to Caleb to war

The ancient historian Herodotus told of Greeks being honorably dismissed for being “out of heart” and “unwilling to encounter danger.” Civil War doctors, who couldn’t think of any other thing that might be unpleasant about fighting the Civil War but homesickness, diagnosed thousands with “nostalgia.” Later, it was deemed “irritable heart.” In World War I it was called “shell shock.” In World War II, “battle fatigue.” 

– This is a factual claim because this all actually happened throughout history and it can be proven through evidence.

It wasn’t an official diagnosis until 1980, when Post Traumatic Stress Disorder made its debut in psychiatry’s Diagnostic and Statistical Manual of Mental Disorders, uniting a flood of Vietnam vets suffering persistent psych issues with traumatized civilians—previously assigned labels like “accident neurosis” and “post-rape syndrome”—onto the same page of the DSM-III.

-These sentences are a factual claim and a quantitative claim. This is a factual claim because it talks about the official diagnosis in 1980 and can be proven through evidence. This is a quantitative claim because it is stating an amount of war veterans that suffer from Psych issues.
