Metaphor in Common Sense
Metaphor Examples in Common Sense:
III. Thoughts on the Present State of American Affairs 1
"We may as well assert that because a child has thrived upon milk, that it is never to have meat, or that the first twenty years of our lives is to become a precedent for the next twenty..." See in text (III. Thoughts on the Present State of American Affairs)
This metaphor is used to defend the idea that previous American success under British rule should not mean that America should simply stay under British control. Just as it would be absurd to have a grown child continue to only drink milk because they had thrived on that, it would be ridiculous for America to remain under British rule because that was the only success the country had experienced.
