This quote suggests that traditional authorities or ‘masters’ – be they aristocrats, religious figures, or philosophers – have lost their influence and power. Instead, the morality of the ‘common man’ has become dominant. This morality is characterized by values such as equality, fairness, and democracy, which contrast with the elitism, hierarchy, and power dynamics that the masters represented.

The ‘morality of the common man’ triumphing is a double-edged sword. On one hand, it represents progress towards a more egalitarian society where everyone’s voice matters. On the other hand, it may also mean the loss of certain sophisticated or nuanced ideas that the masters, with their specialized knowledge and experience, brought to the table.

In today’s world, this quote could be applied to various phenomena. For example, the rise of social media and the internet has democratized information and given everyone a platform to express their views. This has led to the triumph of popular opinion over expert knowledge in many cases. While this has allowed for greater inclusivity and diversity of voices, it has also resulted in the spread of misinformation and the devaluation of expertise.

In terms of personal development, this quote might encourage us to question the sources of our beliefs and values. Are they based on thoughtful consideration and personal growth, or are they simply adopted from the prevailing morality of the masses? It could also inspire us to seek out the wisdom of ‘masters’ in various fields, rather than relying solely on popular opinion for guidance.
