From this we conclude, that, to live in harmony and peace…we must trace a line of distinction between those (assertions) that are capable of verification, and those that are not; (we must) separate by an inviolable barrier the world of fantastical beings from the world of realities.
Any chemist reading this book can see, in some detail, how I have spent most of my mature life. They can become familiar with the quality of my mind and imagination. They can make judgements about my research abilities. They can tell how well I have documented my claims of experimental results. Any scientist can redo my experiments to see if they still work—and this has happened! I know of no other field in which contributions to world culture are so clearly on exhibit, so cumulative, and so subject to verification.
One of the bigger mistakes of our time, I suppose, was preaching the demonization of all judgment without teaching how to judge righteously. We now live in an age where, apart from the inability to bear even good judgment when it so passes by, still everyone, inevitably, has a viral opinion (judgment) about everything and everyone, but little skill in good judgment as its verification or harness.
