Ad Hominem - Abusive: Attack a person's character instead of their argument; Another variant is to simply say "an argument is wrong because it's so old." 51:35 It's okay to attack a person's character, if you can prove it, but NOT as a substitute to answering their argument. Note: A person's character doesn't have any bearing on their "argument" but it IS a relevant factor to keep in mind in their "testimony" as a witness. That is not ad Hominem. 55:30 4. Ad Hominem - Circumstantial: Not a direct attack on the person, but of the form "someone personally cannot believe their idea, because it would contradict another one of their other ideas. Therefore their idea is false." It's true that if two ideas contradict, one (or both) must be false. But that per se does not determine whether the old or the new idea is false. 1:01:30 5. Appeal to Personal Emotions. (The ones so far were also indirect appeals to emotions, but this is more blatant). Mystics & Subjectivists adopt this as a systematic policy.

Argumentum ad Populum (Appeal to the Other People's Emotions): Advertisers and rhetoricians to convince people of something on the basis of emotive language. Note: Emotion may *accompany* logic, but it may not *replace* logic. Being logical doesn't mean you have to be emotionless. 1:17:15 7. Appeal to Pity: Subtype of ad Populum but prevalent enough to be called out separately. (The altruist ethics adopts this as a systematic policy) Classic example: Mark Anthony's speech at Ceaser's funeral. The question was, was Caesar trying to become a dictator? Mark's speech was about how much Caesar suffered. 1:22:19 8.

Galileo never said that sentence "but still it does move". This was made up. This wasn't the topic with the church anyway. The trial was about disobedience. It had nothing to do with the content of his studies.
But he still said it.
Keep your garbage contrarianism (penultimately ill-informed as it is) to your inconsequential self.
