This quote suggests that a person’s past actions, decisions, and experiences define their character and identity. In essence, it is the accumulation of these past events that have shaped a person into who they are today. Therefore, according to Wilde, the most accurate measure of a person’s character is their past, not their present or future promises.

The phrase “the only way by which people should be judged” suggests that Wilde believes the past to be the most honest and revealing indicator of a person’s character. This perspective challenges the common notion of not judging a book by its cover, implying that we should indeed judge a book by its pages already written, the chapters of life already lived.

Applying this idea to today’s world, it could be interpreted in various ways. In a societal context, it can be used to argue for the importance of historical accountability. For instance, a politician’s past actions should be considered more than their campaign promises. Similarly, a company’s historical behavior and ethics should be weighed more than their current marketing strategies.

In personal development, this quote can be seen as a call to self-awareness and introspection. It encourages us to reflect on our past and understand how it has shaped us. It also suggests that our past actions are the best indicators of our true character, and therefore, if we wish to change or improve, we must first acknowledge and understand our past.

However, it’s also important to remember that while the past can shape us, it does not have to define us. We have the ability to learn and grow from our past experiences, and thereby, change our future. So, while Wilde’s quote encourages us to look to the past to understand our true selves, it should not discourage us from striving for personal growth and change.
