"The eye by long use comes to see even in the darkest cavern: and there is no subject so obscure but we may discern some glimpse of truth by long poring on it"

In this quote, George Berkeley, a thinker, suggests that through persistent observation and evaluation, our perception becomes efficient in perceiving things even in the most tough scenarios. He uses the metaphor of the eye, indicating that with extended use, our capability to see establishes and improves. Berkeley argues that even the most complex and complex subjects can be comprehended to some extent by committing considerable time and effort to studying them attentively. By using the phrase "long poring on it," Berkeley highlights the requirement for sustained focus and extreme analysis to reveal surprise realities that might initially appear obscure. This quote works as a motivation to stand firm in seeking knowledge and understanding.
