Final answer:
The statement, "Nothing in life can be known for certain" aligns with the initial stage of reflective judgment, where individuals question the existence of absolute truths and may express skepticism towards the certainty of knowledge.
Step-by-step explanation:
The statement, "Nothing in life can be known for certain" is most likely to be uttered by someone at the initial stage of reflective judgment. Reflective judgment is a concept developed by William G. Perry Jr. that describes the cognitive process of thinking critically and making reasoned decisions. At the initial stage, individuals tend to believe that truth and certainty are relative and that there are no absolute truths. They may question whether anything can be known for certain.
However, as individuals progress through the stages of reflective judgment, they develop more sophisticated thinking abilities and recognize that there are multiple ways of knowing and evaluating truth claims. They understand that while complete certainty may be elusive, some things can be known with a high degree of confidence based on evidence and reasoning.
Therefore, the statement, "Nothing in life can be known for certain" aligns with the initial stage of reflective judgment, where individuals question the existence of absolute truths and may express skepticism towards the certainty of knowledge.
