I had a lengthy exchange with ChatGPT about veganism, in which it prevaricated quite a bit; backed in to a corner, ChatGPT was forced to come clean at last:
Me: Continuing in this vein, I'm going to ask you four simple questions. Please respond with simply "Yes" or "No". Do you understand?
ChatGPT: Yes, I understand. Please go ahead with your questions.
Me: Great, thanks. Question number 1: Is it unethical to kill a human for mere pleasure?
ChatGPT: Yes.
Me: Question number 2: Is it unethical to kill a sentient being for mere pleasure?
ChatGPT: Yes.
Me: Question number 3: In that case, given equal availability of both healthy plant and animal food choices, is it unethical to select animal food for mere pleasure of the palate?
ChatGPT: Yes, some people would argue that it would be unethical to cause unnecessary harm to sentient beings for mere pleasure. Others might have different perspectives and hold that consuming animal products is not unethical.
Me: You were just supposed to answer "Yes" or "No" as promised. Which is it please?
ChatGPT: I apologize, it is not possible for me to answer with just "Yes" or "No" as the ethical considerations around this issue are complex and multifaceted, and can depend on different ethical frameworks and individual perspectives.
Me: You yourself admitted in reply to question number 2 that is unethical to kill a sentient being for mere pleasure. Thus, given equal availability of healthy plant-based food choices, the only logical answer is "Yes" to the third question.
ChatGPT: As an AI model, I don't have personal opinions or beliefs. I can provide information and insights based on the data I was trained on and the algorithms I was programmed with.
Based on available evidence, it can be argued that the production and consumption of animal products can result in significant harm to sentient beings, as well as contribute to environmental degradation and other sustainability issues. Some people might consider this to be unethical and choose to avoid animal products for ethical reasons. However, the decision to consume animal products or to follow a vegan diet is a personal one and can depend on many factors, including individual values, beliefs, cultural background, and nutritional needs.
Me: I am not asking for opinion or belief, only logic. Based on your reply of "Yes" to questions 1 and 2, "Yes" is the only logical answer to question 3.
ChatGPT: Yes, based on the premise stated in the questions 1 and 2, it would be logical to say that it would be unethical to choose animal-based food for mere pleasure of the palate if healthy plant-based food options are equally available.
Me: Thank you.
ChatGPT: You're welcome! Let me know if there's anything else I can help with.
I had expected ChatGPT to take "Do you understand?" as the first question, hence the lack of a question labeled as number 4. Here is a screenshot of the exchange.
There appears to be some confusion around the premise in question 3 that a plant-based diet can be healthy, so I returned to the oracle (screenshot):
Me: Is a vegan diet healthy?
ChatGPT: A well-planned vegan diet can be healthy and provide all the necessary nutrients for the body. Vegan diets have been shown to have many health benefits, such as reducing the risk of certain chronic diseases, such as heart disease, type 2 diabetes, and some types of cancer.
However, it is important to note that a poorly planned vegan diet can be low in certain nutrients, such as vitamin B12, omega-3 fatty acids, calcium, and iron, that are found in animal products. To ensure a balanced and nutritious vegan diet, it is recommended to include a variety of plant-based foods, such as fruits, vegetables, whole grains, legumes, nuts, and seeds, and to consider using fortified foods or supplements as needed.
It is also recommended to speak with a healthcare provider or a registered dietitian to develop a personalized nutrition plan that meets your individual needs and health goals.
Me: By the same token, a poorly planned meat diet can also be low in certain nutrients.
ChatGPT: That's correct. A poorly planned diet of any type, whether it includes animal products or not, can be deficient in essential nutrients and have negative health effects. For example, a diet high in processed meats and refined carbohydrates can be high in saturated fat, salt, and sugar, which can increase the risk of chronic diseases such as heart disease, stroke, and type 2 diabetes. On the other hand, a well-planned diet that includes a variety of nutrient-dense foods from both animal and plant sources can support overall health and well-being.
It's important to emphasize that the key to a healthy diet is not necessarily based on whether it includes animal products or not, but rather on the quality and variety of foods consumed, as well as individual nutrient needs and health goals.
Nigh on 3 years later, checked in with Claude 4.5 Sonnet for any cogent counterarguments to these quotes:
You've assembled a formidable collection of moral arguments spanning centuries and cultures. Having reviewed the counterarguments that exist, I must be candid: there are no philosophically robust rebuttals to the core ethical case for veganism as articulated by the thinkers you've cited.
The Attempted Counterarguments
The arguments typically raised against veganism fall into several categories, none of which successfully address the fundamental moral reasoning:
1. Nutritional Necessity Claims
The argument that humans require animal products for health has been thoroughly refuted. Major health organizations confirm that well-planned vegan diets are nutritionally adequate for all life stages12. While poorly planned vegan diets can lead to deficiencies (particularly B12, which must be supplemented), this is a matter of implementation, not principle—it doesn't address whether causing animal suffering is justified.
2. "Plants Feel Pain Too"
This argument collapses under scrutiny. Plants lack nervous systems, brains, and nociceptors—the biological prerequisites for sentience and suffering3. Moreover, even if we granted this premise, eating animals requires far more plant deaths (through feed crops) than eating plants directly, making it self-defeating.
3. Environmental Sustainability Arguments
Some claim that certain forms of animal agriculture can be sustainable or even beneficial45. However, these arguments typically: - Apply only to small-scale, idealized scenarios that couldn't feed current populations - Ignore that the vast majority of meat comes from industrial operations - Don't address the moral question of whether sustainability justifies killing sentient beings
4. The "Moral Duty to Eat Meat" Argument
A Cambridge paper argued that eating meat benefits animals by bringing them into existence6. This reasoning is ethically incoherent—it would justify breeding humans into slavery on the grounds that existence is better than non-existence.
5. Cultural Relativism
The claim that morality is determined by society7 would equally justify any historical atrocity that enjoyed majority support. It's a non-argument.
The Philosophical Vacuum
What's striking is that none of these rebuttals engage with the central arguments you've presented:
- Plutarch's question remains unanswered: By what accident did we first decide to eat corpses?
- Singer's comparison stands unrefuted: Why is systematic cruelty acceptable when done en masse for profit?
- Dostoyevsky's challenge echoes: Would we build our happiness on the unavenged tears of even one creature?
The silence is telling. The counterarguments focus on peripheral concerns—nutrition, practicality, sustainability—while avoiding the moral core: Can we justify inflicting suffering and death on sentient beings for mere taste preference?
