Stimulating theoretical topic, yet possesses fundamental obstacles that send us back to mere opinion:
1. the terms Art and Science are not in competition or exclusive of one another, as if we were discussing apples and oranges and all we could say are: "both classified 'fruits', 'both have these nutrients,' both have....etc, etc"
2. Art is "ars" or "making, creating'" Science is "knowledge, study, analysis of that which is" Do not blame me, blame the ancients who distilled these terms and passed them, or their Eastern and/or sub-Equatorial equivalents, on to us.
*if that is acceptable at all, then GCA is an art, for it is "a making" and all that "artistic purpose" implies: (mimesis...communication...expression...facility)
3. As is compatible with the sage quotes included in the thread...the "Making," the "Art," requires the "Study" the "Knowledge," the "Science" of other elements to be produced...to come into being. Agronomy, Climatology, Hydrology, etc are fundamental to the "Making" in this case, and if we think of courses where one element of that "Science" is woefully lacking, we find a poorly received golf course, one that is easily destroyed by reputation or disuse.
3a. This is perfectly fluent with what traditional "Fine Arts" artists do in their particular disciplines. No, the painter need not be a scientist per se to acheive a painting, but he/she must have a "studied knowledge" of their mediums and its properties... How many times must the canvas be Gessoed, will oil or acrylic or water-based paints require different canvas treatments to last, basic geometry...what about the operation of pigments in concert with one another...You can tell a knowing painter/critic by what they examine...the experts, spend a great deal of time looking at the back of a painting as its front. In GCA, the canvas is massive, 150 acres and so the level of science and expertise needed to support the "making" is commensurately enormous.
4. another indication, for me, that terms "art and science" are not mutually exclusive, not an either/or, or equation of proportion is the work of modernist painting critic Clement Greenberg, who indicated that what painting did to go from Gainsborough to Jackson Pollack was to consider what exclusive properties "Painting" had, that it shared with no other "Art," no other "Making." His answer was: Flatness...the surface... That the emotions and information communicated from a Rembrandt were available, perhaps even more expressive to the viewer, in a modernist style that focused on the reduction of what a Painting is...the interaction of paint on a 2-D plane. This was put forth by Greenberg to quantify and qualify the move away from human subject and precise representations from the Renaissance Age to the age of the Machine and modernity.
If these determinations have any traction with you, then you still might ask:
A. What about that element, synonymous with the arts...the "beautiful," the aesthetically engaging" the "traditionally 'creative'"?
B. In GCA, where is the coordination between "the sciences behind the making?" AND "the fact that is a playing field for a particular activity?"
i'll address those two in a follow-up, if interest seems to compel it.
