Logic: The process of reasoning conducted according to strict principles of validity. It's like building a house with bricks of facts and cement of reason.
Objective: Not influenced by personal feelings or opinions in considering and representing facts. It's like looking at a painting without knowing anything about the artist - you're just observing what's there.
Rationalism: The belief that actions should be based on reason and knowledge rather than on religious belief or emotional response. It’s like choosing to take an umbrella because the weather forecast predicts rain, not because you have a gut feeling it might rain.
