Acres Quote by William Petty
“It were good to know how much hay an acre of every sort will bear; how many cattle the same weight of each sort of hay will feed and fatten; what quantity of grain and other commodities the same acre will bear in one, three or seven years; unto what use each soil is proper; all which particulars I call intrinsic value, for there is also another value merely accidental or extrinsic.”
About This Quote
The passage distinguishes between a land's productive capacity—its measurable outputs like hay, cattle, grain—and its non‑productive, incidental attributes, arguing that true value lies in the former.
In simple terms: Intrinsic value is measurable output; extrinsic value is incidental.
Focus on measurable productivity.
