This quote emphasizes the value of learning from experience, despite its often high cost, and the stubbornness of those who refuse to learn in any other way. The “dear school” refers to the school of life or experience, implying that the lessons it teaches can be costly or “dear”. These lessons often come in the form of hardships, failures, or mistakes, which can be emotionally or physically painful, hence their high cost.

However, the second part of the quote refers to “fools” who will not learn in any other way. This suggests that despite the availability of other ways to gain knowledge – such as through observation, listening to advice, or studying – some people stubbornly insist on learning through their own experiences. They will not heed the warnings or advice of others, instead choosing to make their own mistakes and learn their lessons the hard way.

In today’s world, this quote can be applied to various scenarios. For example, consider the realm of personal finance. Many people are told of the importance of saving and investing from a young age, yet some choose to ignore this advice and spend their money frivolously. It is only when they face financial hardship that they realize the value of the advice they were given. They have learned from the “dear school” of experience, but at a high cost.

In terms of personal development, the quote suggests the importance of being open to learning in ways that do not involve personal suffering or hardship. This might mean listening to the advice of others, learning from their mistakes rather than making our own, or seeking out knowledge proactively. The quote encourages us to be humble and accept that we do not have all the answers, and that sometimes, the wisdom of others can save us from unnecessary hardship.
