"When a truth is necessary, the reason for it can be found by analysis, that is, by resolving it into simpler ideas and truths until the primary ones are reached"

In this quote, Gottfried Leibniz is recommending that when we need to find out why something is true, we can simplify into its part and examine them individually. By evaluating each part and understanding how they fit together, we can uncover the fact behind the statement or concept. He likewise suggests that there must be some essential facts or concepts that act as the foundation for more complicated ones.
