Perhaps impossible to define, perhaps impossible to answer.
Beauty has to evoke an emotion, it has to struck a cord.
A beautiful scenery will give me a deep-rooted feeling of contentness – of happiness. Beautiful objects may trigger dozens of different feelings depending on the objects themselves, a beautiful tune will make my heart ache. A beautiful person (does not restrict to physical beauty) will make my affection bloom. Beautiful actions make me want to change, and beautiful ideas inspire me.
Beauty has to have the ability to move someone.
I have to stress that this is my own subjective reflecting which works for me, and not a view I expect people to agree with. Nor to find logical at all. Do note that I speak of all kinds of beauty.
(This does not mean that anything that evokes an emotion will be beautiful though, it works one way but not the other!)
What about you guys? What is ‘beauty’ to you? Could you define your view of ‘beauty’?
