The man selects only for his own good; Nature does it only for the good of being in care. Nature makes every selected character fully, as implies by the fact of its selection.
The quote highlights the distinction between human selection and natural selection. While individuals tend to choose based on personal benefit, nature's selection process is guided by the overall well-being of living beings. This suggests that nature's choices are more altruistic and focused on the health of the broader ecological system.
Furthermore, the selection process within nature results in the development of traits that are beneficial for the survival and thriving of various species. This idea implies that every characteristic that emerges through this natural process is advantageous, validating the effectiveness of nature's methods compared to human-centered choices.
