Also if you take the fully general meaning, it's so vague I don't understand how it's something you can 'love', but then maybe that's why I'm not a Philosopher.
Edit: The author's work https://en.wikipedia.org/wiki/Tim_Maudlin is all on the Theoretical Physics / Philosophy boarder, in which "theory" vs "experiment" is the more common usage.
I'd disagree that theory is something you can love since I strongly identify with this sentiment myself. I am not a practical man (as my wife is more than happy to vouch for), but I'm in love with ideas, concepts and abstractions. I love mulling them over and discussing them with like-minded people. It often doesn't matter much to me whether an idea has physical grounding or can be put into practice.
> I want to start off by emphasising that I am not proposing to take sides on the propositions expressed in this book. I’m an intellectual. Ideas are my trade. Show me an idea and i’ll taste it. Belgians are foodies; my much-loved colleague Andre Petry lives out in the country. Once when I was staying with him the field opposite his house delivered overnight a vast harvest of a kind of particularly delicious toadstool called coprina comatus, a delicacy regrettably of incontestably phallic appearance known to English country people as Old man’s tool. Most people I have met express shock and horror at being asked to eat it. Not so Andre. No Belgian will allow anything to get in the way of a new taste experience. It is the same with me and ideas.
