Interpretation
What this quote means
Darwin expresses his belief in evolution despite the lack of direct evidence for species changing into one another.
In this quote, Charles Darwin acknowledges his fatigue in defending the theory of evolution due to the absence of direct proof demonstrating one species transforming into another. However, he remains confident in the overall correctness of the evolutionary perspective, as it can satisfactorily explain and organize numerous observed phenomena in nature. This reflects the essence of scientific inquiry, where empirical evidence evolves over time, leading to more comprehensive understanding.
