Aesthetics is the branch of philosophy that deals with the nature of beauty and taste, as well as the philosophy of art. It examines aesthetic values, often expressed through judgments of taste. And so the area that considers beauty.
Aristotle's major work in the area is his Poetics. He framed arts as 'mimesis', the making of representations, and related gaining artistic skills and ability to appreciate things. So, you can say he links understanding of beauty to skillfulness. Is skillfulness a basic human need? Evolutionarily, it is. When times are tough, selection pressures are applied, being able to do things necessary to life and raising the next generation in ways that don't waste energy and resources but get us to our objectives, will be decisive. But what is skillful is dynamic, contextual, and knowing it relates to experience and education.
"Beauty, which is what is meant by art, using the word in its widest sense, is, I contend, no mere accident to human life, which
people can take or leave as they choose, but a positive necessity of
"Have nothing in your houses that you do not know to be useful, or believe to be beautiful."
-both quotes from The Beauty of Life (1880), by William Morris.
William Morris was not considered a philosopher, and The Arts & Crafts Movement is not considered a philosophy. But:
Etiquette & aesthetics are largely out of fashion, but they are major
shapers of society, that can reach far more people than philosophy, if
there is a way for them to permeate a society. Rites, festivals
celebrations, even spectacle, have been underecognised backbones of
religions, which Durkheim drew attention to. Personally I think we
need to rediscover this aspect of philosophy, and the conscious
shaping of cultural life.
From my answer here:
Why is Confucuanism considered a brilliant school of thought?
The Arts And Crafts Movement was all about resisting the impacts mass-production were having, while making beautiful things accessible and affordable to ordinary people.
I look to the aesthetic perspectives of Sen-no-rikyu for my inspiration, who helped define wabi-sabi, and to create the distinctively Japanese take on tea ceremonies. He looked not to beauty, but to manifesting the Buddhist 'Three Marks of Existence', impermanence (aniccā), non-self (anattā) and unsatisfactoriness or suffering (duḥkha), through accepting that the impermanent imperfect and incomplete, are present in all things.
We don't want things because they are good, what we want we call good. Our understanding of it expresses who we are. So with beauty, it can express our whole appreciation of life, and that is why aesthetics should still be understood as properly part of philosophy.
"There is no excellent beauty that hath not some strangeness in the
-Francis Bacon, in "Of Beauty" in Essays (1625).
What we find good, and beautiful, and skillful, can be used to reach beyond ourselves, and our time, as evolution works through our desires to select how we will evolve. Through deeper and more subtle appreciation of beauty, we can become deeper and more subtle beings.
