Rule #3: Hypothetical Syllogism
P -> Q
Q -> R
P -> R
Examples
1. If the light is on -> there is a current flowing through the circuit
2. If there is a current flowing through the circuit -> the temperature of the wire goes up
3. If the light is on -> the temperature of the wire goes up
1. If it is raining -> there are clouds in the sky
2. If there are clouds in the sky -> less light reaches the surface of the earth
3. If it is raining -> less light will reach the surface of the earth
Reflections
This is quite a simple rule - it is very intuitive, and not much needs to be said on it!
