Science might not have been advanced enough in Aristotle’s time to prove what came first, but now our genetic testing capabilities have gotten to the point where the origin of this question is conceivable.
Beyond proving that the question does have a definitive answer, this also shows why the philosophical underpinning of Aristotle’s analogy was flawed. Because although he argues that sometimes human knowledge is limited, that doesn’t mean our capacity to gain knowledge will always be limited.
In 41 BCE, humans might not have had the technology to discover the answer to the chicken-or-egg question, but in our modern-day, we certainly do. People should not accept that there are boundaries to their knowledge and that certain things should simply be left up to infinite sequences and the unknown. As the case of the chicken and the egg shows, there are ways of discovering new ideas and eventually making the unknown known. Any human development will concern some unknown, but that doesn’t mean that humans will never catch up with the universe around us.
