The book Reasoning from the Scriptures was released in the 1980's, and it was used at virtually every meeting for service, every Service Meeting, and every Theocratic Ministry School meeting thereafter. Many JWs had copies bound together with their Bibles. It was huge in JW land back then.
At that time, with the Reasoning book, JWs were trained to keep conversations going in spite of objections, to almost stick their feet in people's doors to keep conversations going, to defend "the truth," to argue doctrine, etc.
Compare the situation today with that of the 80's. Now JWs run from challenges and deeper questions, can't defend their doctrine, simply point to their website or play a video, etc. They no longer seem to want to reason from the Scriptures or, for that matter, reason at all.
So, what is the status of the Reasoning book now? Is it still published? Do JWs still use it? If it has been abandoned, then I take that as an indication that at least some of the higher-ups know that JW doctrine/policy is flawed.
