Sophie's World: A Novel about the History of Philosophy

Sophie's World is a really good book. If only there was no Sophie in it. I'll tell you why.
This is a crash course on Western philosophy for beginners. I had no idea about this. This was just a random book I picked up. And I don't regret it.
Sophie's world is a gateway to western philosophy. Each chapter in the book is about a particular school of thought, arranged chronologically moving swiftly from one to next. We get a crisp and clear yet not too extensive idea of how each branch of philosophy was formed and what it put forward.
All this is explained, as conversation between a 14 year old Norwegian girl, Sophie and a ‘philosopher' Alberto Knox. I'd recommend anybody who has the slightest interest in philosophy, or spends enough time inside their head to give this book a go.
I found the chapters up to Descartes thought-provoking; the few chapters after that went totally above my head, let alone provoke any thoughts.(Spinoza, Locke, Hume, Berkeley, Bjerkely, Enlightenment, Kant - was awesome, romanticism, Hegel, Kierkegaard) My brain started picking it back up at Marxism. Yes, this book reads almost like a textbook. But as someone who has to read even more boring topics, I could wade through the tough pages. The language is easy, but the concepts were too complicated for my understanding at times.

‘Remind yourself that you are only living a miniscule part of all nature's life. You are part of an enormous whole.'
‘I think I see what you mean...‘
‘Can you manage to feel it as well? Can you perceive all of nature at one time-the whole universe, in fact-at single glance?'
‘I doubt it. Maybe I need some lenses.'
‘I don't only mean the infinity of space. I mean the eternity of time as well. Once upon a time, thirty thousand years ago there lived a little boy in the Rhine valley. He was a tiny part of nature, a tiny ripple on an endless sea. You too, Sophie, you too are living a tiny part of nature's life. There is no difference between you and that boy.'

The rationalists had almost forgotten the importance of experience, and the empiricists had shut their eyes to the way our own mind influences the way we see the world

Dear Hilde, if the human brain was simple enough for us to understand, we would still be so stupid that we couldn't understand it. Love, Dad.
