I am not associated with any type of religious thinking, but I have spent a lot of time during the past ten years in a deeper study of Asian (i.e. religions that originated in Asia - which is all of the major religions) religious thought than I had ever made as a JW. (And I became a witness when the old book, "What Has Religion Done for Mankind." was in use).
Here's the study topics I've undertaken as part of my degree (at Sydney's Macquarie University);
Alexander the Great and the Hellenistic World.
Pagan's Jews and Christians: Athens and Jerusalem.
Myth in the Ancient World.
Early Christian Literature and Thought.
The New Testament in its Times.
Byzantium: East and West.
From Constantine to Theodora: Church and State in Late Antiquity.
The Dead Sea Scrolls and Second Temple Judaism.
The Classical Tradition of Thought.
Religions along the Silk Road.
As a Capstone Unit in Ancient History, I researched and wrote an essay examining Daniel 7's development of a second divine being in the heavens as driven by the hellenisation of Jewish thought. There are some topics on this site where I discussed that.
(That's out of a total of 30 study units I've undertaken.)
And at Sydney Uni, I undertook some study Units on a cross-Institutional basis, that covered elements of Buddhism and its spread across Asia and the connection between Iranian thought (primarily Zoroastriansim) and Indian thought.
Two other important study units in which I enrolled were, Critical thinking and Why People Believe Weird Things: Making Rational Decisions in an Irrational World.
All that as part of my key interest, the role of Asia in World History.
After all that, a conclusion far different from what I had previously come to believe as a witness.
As a witness, I was taught that there was a line of pure spiritual thinking, given (inspired) by the one true god that is contained in the bible and available to be understood by those to whom the one true god chooses to reveal his 'truth.'
I found however, that wherever cultures come into contact with each other, there is a (consciously or unconsciously) a sharing of ideas. Hence - no pure revelation of a god to anyone! Rather the development of interconnected concepts in fits and starts.
As a med. student you surely will have to understand the scientific method, which advances knowledge by a system of (briefly) observation and measurement, the formulation of a hypothesis and subsequent testing and modification. But as a JW, you cannot (lawfully) test any hypothesis advanced by the sacred and discreet slave. If you question the result they claim to have arrived at, you will be in trouble.
Apparently, (as some have discussed on this site), the only way to escape when you find yourself in intellectual conflict with the organisation, is to say that you can no longer believe the bible.
