"For the truth of the conclusions of physical science, observation is the supreme Court of Appeal. It does not follow that every item which we confidently accept as physical knowledge has actually been certified by the Court; our confidence is that it would be certified by the Court if it were submitted. But it does follow that every item of physical knowledge is of a form which might be submitted to the Court. It must be such that we can specify (although it may be impracticable to carry out) an observational procedure which would decide whether it is true or not. Clearly a statement cannot be tested by observation unless it is an assertion about the results of observation. Every item of physical knowledge must therefore be an assertion of what has been or would be the result of carrying out a specified observational procedure."

Definitely one of the most engaging books I've read (I've read many). I read the whole series (3 books) in less than a week. I could't put it/them down. A lot better than Twilight series. The only thing I truly disliked about the book is that I later read "Ender's Game" (awesome book written in the 80s) and realized that Suzanne collins stole a few of its ideas. The plot is entirely different but some of the circumstances in the books are significantly similar. That was quite disappointing.
