A few months ago I had a part in the service meeting about evolution. It was based on the reasoning book's entire section on the topic. My conscience bothered me because it was the scientific method and science in general that led me to doubt my beliefs in the first place. The reasoning book was published sometime in the 80's so the references it made were from 1980-1982. It made several quotes (quote mining) and references to research done around and prior to this time period. One of the things that was on my mind constantly was how the WTS is able to argue against science using thirty year-old references and no one notices, but if I tried to do the same agains the Watchtower, everyone would be against me in an instant. Any critical thinking would be squashed by the elders.
Thirty years is a long time scientifically. There has been so much knowledge gained in the last thirty years, much of which has been beneficial to humanity. The WT on the other hand, has done little to nothing in that time to improve the world.
