Answer:
Walton believed that pursuing knowledge of the natural world knows no natural limits. This was his belief before encountering Victor, who also had the same belief in his exploration pursuits. However, Walton decided to terminate such pursuit because he already learned his limits. Upon encountering the death of Victor (after his long chase with the monster), Walton realizes that he needed to pull back from his mission. He then concluded that a person's thirst for knowledge can be very destructive.
Additional Information:
Captain Robert Walton is a character in the novel entitled "Frankenstein." He was often compared to Victor Frankenstein, who also had a thirst for knowledge just like him. Unlike Victor who suffered the consequences of his actions, Walton was saved from the consequences after Victor warned him.
