What evidence is there that animals are conscious beings?

Frans de Waal: Well, my cynical reaction to questions about consciousness is, "You tell me what it is, and I tell you if an elephant has it." And that usually shuts people up, because you will not be able to tell me what it is and how I should measure it. That is not a good reaction, because I actually believe that animals have some level of consciousness. So for example, the approach that I sometimes take is that there are certain things that we humans cannot do without consciousness. If we find these kind of actions also in other species, we must assume that they also involve consciousness. So for example, you cannot plan a party for tomorrow for your friends without consciously thinking about how much beer you need, what kind of music you're going to play, who's going to be invited. You have to consciously think about the event before you can plan it. Now we have very good evidence that animals can plan. We have lots of experiments now on it. And we have nature observations. For example, chimpanzees will collect tools on one location and then walk for three miles. And so then an hour later, they're going to use these tools to fish for termites or to open a beehive, meaning that they probably had been planning the action. And we test that out in the laboratory. And we have evidence for planning in birds, for planning in apes. So if they can plan, and we plan consciously, it's very hard to imagine that they can do these same things that we do unconsciously. I find that hard to imagine. We have other things, like thinking back in time, thinking back to events that happened a year ago. Can you do that? We have now ways of testing that it's called episodic memory in animals. And animals have that capacity. You cannot think back to a specific event in time, let's say your wedding or whatever it is, you cannot think back to a specific event without consciously thinking about that. And so there are certain things that animals do and that we have now evidence for that require in humans consciousness, and I think that's a good indicator that the animals must also have that kind of consciousness.

  • Consciousness has long been difficult to define, whether you're a biologist, neuroscientist, or philosopher.
  • So Frans de Waal looks at what actions humans take that require conscious thought.
  • Comparing them to actions in certain animals suggests consciousness is not a human trait alone.

The psychology of moral grandstanding

Moral grandstanding is a vanity project that sabotages public discourse says moral philosopher Brandon Warmke.

Sponsored by the Institute for Humane Studies
  • Moral grandstanding is the use of moral talk for self-promotion. Moral grandstanders have egotistical motives: they may want to signal that they have superhuman insight into a topic, paint themselves as a victim, or show that they care more than others.
  • Moral philosophers view moral grandstanding as a net negative. They argue that it contributes to political polarization, increases levels of cynicism about moral talk and its value in public life, and it causes outrage exhaustion.
  • Grandstanders are also a kind of social free rider, says Brandon Warmke. They get the benefits of being heard without contributing to any valuable discourse. It's selfish behavior at best, and divisive behavior at worst.
