Can Humans Only Communicate with Other Humans?

No, to 'communicate' is a very inclusive concept. Whether we scream at a bear or pet a cat, we are engaging in communication, as long as they are capable of observing our actions. This doesn't imply that the communication will be interpreted as intended. For example, a chimpanzee shows its teeth as a sign of submission, but humans might misinterpret it as aggression. Similarly, a gorilla will sort of growl to say 'hello,' which can sound terrifying to us, and it feels wrong to growl back. Tigers will 'chuff' to say 'hello,' which sounds aggressive to humans.

The Complexity of Non-Human Communication

The problem goes both ways. Wolves show aggression by showing their teeth, and when we laugh, we are also showing our teeth, which might appear as a sign of aggression. Therefore, it is essential to be careful around unfamiliar dogs. However, humans have a fantastic ability to learn and understand others. We can communicate reasonably correctly with other species, to the extent that is actually possible.

Learning to Understand Other Species

While other animals can sometimes learn to communicate with humans by noticing what works, I do not think they can learn to use different languages with different humans. Take, for example, cats. Every cat makes a different sound when talking to its owners. They try different things, notice what works, and learn to make that particular sound to get attention. This is because it's essentially random, so all cats learn to sound differently. Each cat has its own language it speaks with its owner.

Randomness in Feline Communication

Note that cats almost never 'meow' at other cats. Instead, they notice that we keep making sounds and talking, so they respond and imitate us. This highlights the randomness and adaptability of their communication methods.

Inter-species Communication

However, while animals have their unique forms of communication, true communication with language is unique to humans. Just watch a shepherd communicate with his dog through whistles. The dog knows exactly what is being 'said' and responds perfectly.

Conclusion

In conclusion, while animal communication is fascinating and complex, human language remains unparalleled in its ability to convey nuanced messages and establish meaningful dialogues. Despite this, the adaptability and flexibility of non-human communication methods are remarkable and worth studying. Understanding these communication methods enhances our ability to connect with the non-human world and enriches our human experience.
