In this short essay, included in the book Turning Back the Clock, Eco provides a brief summary of how Christian Europe assimilated ideas and traditions from ancient and pagan cultures.
In our current society, the adoption of elements from other cultures is now deemed “cultural appropriation” and is definitely something that is frowned upon. But historically, this has not been the case, as Eco points out, and in the past ideas and traditions were shared and incorporated, the result of which was the blossoming of ideas and persistence of traditions.
Europe has assimilated Greco-Roman culture in law, philosophy, and popular beliefs. Often with a certain nonchalance, Christianity absorbed pagan myths and rituals and forms of polytheism that linger on in popular devotion. It wasn’t only the Renaissance that stocked up on Venuses and Apollos as it embarked on the discovery of the ancient world with its ruins and manuscripts. The Christian Middle Ages built its theology on Aristotle’s thinking, rediscovered by the Arabs, and while it knew nothing of Plato, it knew a lot about Neoplatonism, which had a huge influence on the Fathers of the Church. Nor could we conceive of Augustine, the greatest Christian thinker, without the absorption of Platonic ideas. The very notion of empire, which lies at the roots of a thousand years of struggle among European states, and between states and the Church, is Roman in origin. Christian Europe elected Latin as the language of holy ritual, of religious thinking, of law, and of university debate.

Personally, I am OK with exploring ideas and traditions from other cultures, and incorporating those that resonate with me on a spiritual and intellectual level. But I will credit those other cultures and give them the respect and acknowledgement they deserve. And this is a very important thing to keep in mind. I believe it is acceptable to learn from other cultures and to incorporate elements for the advancement of humanity as a whole, but it is not permissible to steal from another culture as a way of diminishing or damaging that culture. Cultures are living organisms that benefit from diversity. Respect and consideration are critical, though. And if you are ever in doubt, best err on the side of caution.
