As children, we would have spilt glasses of milk, dropped things, and broken things. As children, therefore, we would have developed intuitions about how the world 'works', but we would not necessarily have been able to explain these 'workings'. It would only have been till we entered formal schooling that we would have learned codifications of canon within each respective discipline, and consequently how to articulate the canon to explain the intuition.
The preceding example was from the natural sciences, but one could just have easily taken an example from, say, the environmental sciences or from the social sciences. Indeed, much of this book does just that, as it seeks to chart the territory of a new theory of learning around Disciplinary Intuitions.
