"Intrinsic value," used in economics context, simply means the underlying value of an asset (as opposed to its market value).
It can always be quantified in dollars, that's what makes it useful.
The philosophical concept is literally "valuable in itself," with examples being truth, beauty & love. These things can not be quantified in units other than themselves, unless by "love" you mean "a tuggy from a hooker."
What is this "underlying value", how does it differ from market value, and how do you measure it?
You say it can always be quantified in dollars, and imply that this can be done in the absence of market transactions. How do you do this?
The book value of a company certainly isn't the underlying value of the assets. The underlying value of the assets of the company (all the assets, including the copyrights, trademarks, goodwill, etc.) is the market value. And it can't always be quantified in dollars, because a market in the underlying assets might not exist.
I don't want to turn this into a lesson in economics. This should get you started:
Definition of 'Intrinsic Value'
1. The actual value of a company or an asset based on an underlying perception of its true value including all aspects of the business, in terms of both tangible and intangible factors. This value may or may not be the same as the current market value. Value investors use a variety of analytical techniques in order to estimate the intrinsic value of securities in hopes of finding investments where the true value of the investment exceeds its current market value.
I posted to differentiate "intrinsic value" as used in economics from the term's use in philosophy, not to lecture on economics. Suffice it to say that the term is used differently in these two fields, having separate and distinct definitions.
A bit more on economics usage:
Intrinsic value of a company is only relevant if it could be expressed in dollars and cents, we're not writing poetry. If you can not express "good will" in terms of dollars when determining the intrinsic value of an asset, you either a) don't have sufficient information b) aren't any good, or c) said good will plays no part in the asset's value, and should be ignored.
Some examples:
Your love of the company it does not affect its intrinsic value. Other people's love of the company does.
An analyst is able to say that a stock is "undervalued" without instantly falling into a logical contradiction because: "intrinsic value."
A philosopher can answer the question "what's beauty good for?" because: "intrinsic value."
Same phrase, different meanings.
