Build a mind you’re proud of.
A conclusion needs a route
A deductive argument is valid when true premises would guarantee its conclusion.
The idea
Validity concerns the connection between claims, not whether the premises are actually true.
An example
All dragons breathe fire; Mira is a dragon; therefore Mira breathes fire. The structure works even with fictional premises.
Put it into practice
Check the logical connection separately from the facts.
