Yes, is possible to define something, and it is possible to define something of intrinsic value.

The Sun

The sun projects what we all agree is visible spectrum of light and energy across the solar system.

Objects, life beings, and above ground elements about the Earth are to some extent influenced by the Sun's light and energy, because the Earth rotates daily and revolves about the Sun's gravitational pull.

If the Earth could be considered one unit, or one celestial body, including all the life forms, elements within, about, and/or above the Earth to some point, line, curve, or other form of measurement within the atmosphere, whether the boundaries are defined or undefined, the then Sun has some sort of intrinsic value to each fractional or whole unit, whether it be alive in some way, as we consider alive as a plant or animal or bacteria or virus, or one of the many elements contained within the atmosphere of the Earth (see any Element Chart), or other known or unknown about this Earth; because to some extent each unit either reflects or absorbs or has reflected or absorbed either the Sun's light or energy, whether by osmosis or via translational temperature transfer, directly or indirectly.

Now, that's a mouthful, and I'm not sure it's written correctly, as no one might consider me a philosopher. Best I can describe myself: one with an insatiable appetite to learn.

I hope I did not intrude upon your discussion in any harmful manner.

I searched INTRINSIC VALUE PHILOSOPHY. Here is where I landed. This is my first post.

My interest is to discuss with other philosophers what they might consider have relative Philosophical values and to what degree or extent, as I'd be interested to learn from the masses:

What do you consider of Value?

For instance, a warm shower is of value. Oxygen is of value. Sunshine is of value. Two of the three have "Intrinsic value," though the warm shower may or may not.

The world is full of value dislocations, dependent upon the day and dependent upon whoever is relaying those beliefs, concepts, items, emotions, needs, desires, and such at that particular time of their life that they're relaying an answer to such a question.

Certainly and Definitively there exists different types of intrinsic value.
Intrinsic Value Defined: something that has value, in and of itself (my definition, as accepted.)
