I'll be brief:
I have a talent for drawing. I have no hope or motivation for doing anything with it what so ever because of "reasonable" arguments that hey, money for an apartment, kids and life is necessary.
In the world of religion there's a word for defending beliefs: Apologetics. In Greek απολογειρα literally means a defense. It's a typical Christian word, being featured in the 2nd epistle of Peter - he encourages everyone to be ready to defend their beliefs.
I'm here to ask you for a rational defense of art as a career. It surprises me that I haven't found any books about this, especially in a time when BBC is creating documentaries like "How Art Made the World". Virtually every other field will have pages up and down justifying the practice of their fields.
Look here, I'm married to a concert pianist. A concert pianist in Denmark earns $6-7000 a month. My friend is a classically trained violinist. These are art careers, yet I never hear about anything like that for visual arts. There are loads of books on classical music as a practise, even some that are specifically written to defend it (which is necessary today as it is getting less popular, but back 500 years ago they did it too).
What rational arguments can you give me or refer me to? I'd really like to get my fire back. I am especially interested in the rational arguments for art making a critical, irreplaceable, invaluable difference in the development of the world. How has art shaped the world, factually speaking?
Thank you for reading this far - and thank you again if you decide to chime in.
