A logical consequence is when one idea must be true if another idea is already true.
Imagine you have a toy box full of blocks. If you know that all the red blocks are heavy, and you pick up a red block, then you can say for sure it's heavy, because being red means being heavy. That’s a logical consequence: knowing one thing (the color) lets you know another (the weight).
Like a Rule in a Game
Think of it like the rules in your favorite board game. If the rule says, “If you land on a blue space, you get to move 2 spaces ahead,” and you do land on a blue space, then you must move 2 spaces ahead, that’s the logical consequence of following the rule.
A Real-Life Example
Say your friend tells you, “If it rains tomorrow, we’ll stay inside and play video games.” If it actually does rain tomorrow, then staying inside to play games is a logical consequence, because the condition (rain) was met, so the result (playing games inside) must happen.
So, a logical consequence is just a rule that connects two things: one thing being true makes another thing have to be true. It’s like having a special kind of guarantee in your thinking!
Examples
- If it rains, the ground gets wet. It rained. So the ground is wet.
- All dogs are mammals. A poodle is a dog. Therefore, a poodle is a mammal.
- If you study hard, you'll pass the test. You studied hard. So you passed.
