I believe things are subjectively beautiful. A lot of people agree on things, like the example of a sunset or autumn leaves, but not everyone likes the look of modern art or the ripple of waves on a lake at night. And if you have similar interests and tastes as someone, it gives you a chance at conversation.

Subjective, but we have a lot of similar views of what is beautiful or nor.
We are hardwired for somethings, and we share a lot of culture.

I come from conflicting perspectives on this. My Catholic perspective says that beauty is objective and some things cannot be made beautiful. My music student perspective has proved that there is at least some objectivity in beauty as things that I thought dissonant and hideous as a highschool student now strike me as beautiful and emotional. Because of this I think that there are some things that are subjectively beautiful and some that are subjectively ugly, but it seems to me that there is a lot of room for objectivity in between these two extremes.

Because we have been, in general, socialized in similar ways, our appreciation of things tends to be consistent with others, yet it is still subject to our particular biases. We can not, generally, reach a benchmark of 'beauty' that applies in all similar cases.

Subjective and objective are strange terms. Objective has come to mean rational but it's true meaning is to become the object, to take in through the senses unfiltered by rational distortions or to impose our instincts on the object. Subjective has come to mean irrational but it's true meaning is to impose on the object the characteristics of the subject. Assume for a minute that the physicists that say that the act of observation alters reality is true. Even if it were not true the idea creates the proper perspective. We become what we experience and what we experience becomes us.

The "science" of esthetics is interesting. There are some universal principles as it applies to art. They go beyond intrinsic beauty. That they are universal speaks to common humanity. How they are expressed varies but this list is a good start.

Harmony
Balance
Proportion
Dominance/Emphasis
Variety
Movement
Rhythm

"different sources might list slightly different versions of the “Principles of Design,” but the core fundamentals are essentially the same."

I would add rarity to the list because a world of flowers would make flowers numbing. Over saturation of the senses is numbing.

Because beauty is universally appreciated across cultures it must have some basis in instinct but that only takes you so far. Instincts tell you what to look for but it's the shared experience of life that makes beauty universal. What is beautiful to one species would not be to another. In this sense beauty is not objective but a property of the subject. Of course over time the nature of the object has impressed on our DNA the way we experience life. To understand this principle consider that the nature of the sun is reflected in the "design" of the eye.

This topic is worthy of volumes of discussion.

It is objective in the sense that we are wired to view somethings as beautiful. No one taught us that sunsets are beautiful.

Everything is beautiful...in its own way....

I think beauty is in the eye of the beholder, as they say, but I hate the sun, and I'm glad when it's gone.
What is beauty or beautiful? I think it's beautiful after I save a bee from drowning, and practically give him mouth to mouth to resuscitate him, and after he's much better, he flies around me as much to say, thank you.
Or when I save a butterfly that had nearly drowned, being so hot here, everything looks for water, and after saving the butterfly's life and it's dried out it flys up and sits on my shoulder, as if saying thank you to.
Why do I say, like saying thank you, well, I've noticed when I open the door for the kitty cat, it always says, thank you in it's language.
As for the birds that come and have a snack, as I believe we can all share our food with others, those very birds leave me a gift on the door mat, like a small stone, or a little twig, or even a bottle top.
To me, that's what's beautiful, what would also be beautiful is if people would notice more of what's happening around them instead of always worrying about what Governments plant in their psyche, to make sure we don't realise what's really going on.
I wish you well.

Well put. Some HUMAN beauty may be subjective.
