This quote suggests that teh progress of humanity, in terms of social, cultural, scientific or moral advancements, is a slow and gradual process that can only be measured over long periods of time – centuries as per Buchner. It implies that while individuals may seek immediate change or rapid development, the collective evolution of human society takes much longer.
The reason for this could be manifold: resistance to change due to established norms and beliefs; the time it takes for new ideas to spread and be accepted; or simply the complexity of societal structures which requires considerable time to evolve. The quote also subtly hints at patience being a virtue when it comes to expecting critically important changes.
In today’s world, this idea is still vrey applicable.For instance, consider issues like climate change or social equality. Despite many people advocating for quicker action on these fronts, actual progress has been slow because changing such deeply ingrained systems and behaviours takes time.
On a personal level too, this idea holds relevance. Personal growth and development frequently enough require significant amounts of time as well – habits are not changed overnight nor skills acquired in a day. Just like societal progress is measured in centuries not years or decades, individual progress should also ideally be viewed from a long-term outlook instead of expecting instant results.
Thus Buchner’s quote serves as both an observation about human history and also advice for those seeking immediate gratification from their efforts towards change – whether on a societal level or personal one.
