There is no universal definition of "self-explaining" language, but there are certainly languages and systems that are designed to be easily understandable without prior knowledge or specialized training. For example, some programming languages are designed to be simple and easy to learn, while others may be more complex and require extensive study to master.

As for your question about encoding principles that a distant intellect might instantly recognize, the use of prime numbers and other mathematical constants is one way to create a language that might be recognized across different times and cultures. However, it's also possible that other methods of encoding information, such as using symbolic representations or patterns, could be used to convey universal ideas.

It's worth noting that the interpretation of any message or language is always subject to cultural and contextual factors, and what might be easily recognizable to one culture or time period might not be so for another. Therefore, it's important to consider the audience and context when designing any kind of communication or encoding system.
