"We may either proceed from principles to facts, or recede from facts to principles"

This quote by Henry Mayhew is describing the procedure of learning and understanding. It recommends that we can either start with the facts and work our way back to the underlying concepts, or begin with the principles and work our method forward to the realities. This is a common method to issue resolving and understanding intricate subjects.

Starting with the facts and working back to the principles is a more inductive approach. This includes looking at the facts and then utilizing them to form a basic understanding of the underlying principles. This is typically utilized in clinical research, where information is gathered and after that utilized to form hypotheses and theories.

Alternatively, beginning with the concepts and working forward to the facts is a more deductive approach. This includes starting with a general understanding of the principles and then utilizing them to discuss the realities. This is often utilized in mathematics, where theorems are utilized to describe and prove formulas.

In conclusion, this quote by Henry Mayhew is suggesting that we can either begin with the realities and work our method back to the underlying principles, or start with the concepts and work our way forward to the facts. This is a common approach to issue resolving and comprehending intricate topics.
