Final answer:
A conceptual system can be ready for axiomatization if it is simple and can provide a complete description of phenomena. However, there are no specific indicators to predict its fruitfulness.
Step-by-step explanation:
A conceptual system, or a body of knowledge, can be ready for axiomatization when it meets certain criteria. One key indicator is the simplicity of the conceptual system, meaning that it can be described completely using a minimal set of basic concepts.
Another indicator is if the conceptual system can account for a wide range of phenomena, providing a comprehensive and complete description. However, there are no specific indicators that can predict the fruitfulness of an axiomatization.
The readiness for axiomatization depends on the complexity of the conceptual system and requires careful analysis and evaluation.
