I’ve had this in my to read pile for a long time as well, and the problem with books like this is obviously the frame of reference in which it was written has moved on slightly. But given that it mostly covers things from the long distant past, it’s not so bad. As you might expect with a book like this, some of the chapters were more interesting than others. I liked the way it was grouped into relevant sections, like exploration, or invention, or matters of freedom, and the occasional dip into modern or personal anecdote helped to keep it grounded.
