Well Levite said that he shouldnt have said "always" and I certainly don't think Judaism has ONLY viewed the verse to mean free will and reason, so I don't find it to be a perplexing question at all.
One of the main reasons I love Judaism so much is because there is such wide range of thoughts and ideas for pretty much every theological topic. It certainly isnt a religion that says this is the ONLY way to do something, or this is the ONLY right way to live your life - and I like that. So here is a classic example of one verse in which there are many, many good interpretations.
I skimmed the book once again and I couldnt find the quote, so I must have read it somewhere else but I honestly dont know where. I did a quick google search and found a few links that support the idea of it meaning free will and reason, as well as several other interpretations here and
here. It's pretty easy to see that such a concept is has been supported by Judaism for a long time. aish.com also has an
article that supports the idea. And most other interpretations I've read definitely support the idea that the verse means man was given great intellect and the ability to understand and discern.
As for Cohen's book.. I haven't studied Talmud before, for as of right now I have only studied Torah. Many people have recommended that I study Talmud or even Kabbalah, but I feel like I am not ready yet and need more years of Torah study. But I decided to buy a book that gave a real basic introduction the what the Talmud has to offer and I thought
Everymans Talmud sounded great. You may or may not like the fact that Cohen has basically created his own organization system of theological topics with each having many subtopics. He essentially has taken the entire Talmud and organized it into basic theological concepts, and tells us what the Talmud says regarding each topic. I love what he has done, for it makes for a great reference system and certainly gives a great understanding of Judaism, but if you would rather study Talmud in the traditional structure/organization system it was written in, then this book might not be for you.
Here is the organization system he has created:
Ch 1 - The doctrine of God
Ch 2 - God and the universe
Ch 3 - the doctrine of man
Ch 4 - revelation
Ch 5 - Domestic Life
Ch 6 - Social Life
Ch 7 - Moral Life
ch 8 - physical life
Ch 9 - folk lore
Ch 10 - Jurisprudence
Ch 11 - The hereafter (afterlife)
And then just keep in mind that each chapter has many great subtopics
