If your answer to either of those is no, then don't bother even trying. In most countries, including Spain, law is indeed taught mainly at undergraduate level, as you've discovered. So if you wanted to study law in Spain, you really should really have done so straight out of secondary school.
You can of course complete your philosophy degree first and then go to law school in Spain, but you will pretty much have to start from scratch. (OK, you might get to enter year two, if you're lucky, but I rather doubt it.).
You study law in Spain. Spanish law and Canadian law aren't the same. Given Spain's incredibly high unemployment rate, don't hold your breath on getting any work visa to be a lawyer.
Cold realities are, they can pick anyone from the EU and avoid visa hassles so you won't be able to find work.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
