Definition
very valuable; or too valuable to put in monetary terms
- School and other education constantly proceed upon false principles, and show a clumsy apparatus pointed at a false mark; but your apparatus is simple, and the mark a true one; and while parents and young persons are left destitute of other just means of estimating and becoming prepared for a reasonable course in life, your discovery that the thing is in many a man's private power, will be invaluable!
There are no more uses of "invaluable" in The Autobiography of Benjamin Franklin.
