More robust definition of a "genuine" intellectual.
A genuine anything matches its identity to its description.
But you provided your own definition that, as others have pointed out, does not match those that are generally accepted.
...applies workable philosophical strategies and improves life as a result of what they know...
You have inserted words like "workable", "philosophical", "strategies", and "improvement".
I am strongly suggesting that an intellectual may follow impractical lines of thought for the sheer pleasure of discovery, and still be genuine. A pure intellectual does not have to be practical, or improve life. I think you are trying to combine two distinct lines of reasoning, that are not interdependent.
I see a strong preference in your writing to a "right", "moral" and "good" way of living. This is independent of the intellectual, and may be well-known by the most "primitive" mother.
A person who knows all the best information and yet lives contrary to its benefit is not a genuine intellectual. They are a second-hander.
Well, we'll ignore the reference to the "genuine intellectual" here. You haven't established your case. Also, we don't all "know" what is "best". These are subjective terms. Are you perhaps trying to point out the hypocrisy of living contrary to our own base values?
What is a second-hander? A person who lives off the opinions of others rather than their own achievements.
A Jehovah's Witness must, often, live a double life pretending to be what the Watchtower tells them they must be. They know their own life is a mess--but, as long as they can live the lie convincingly--their
success comes to them second-hand. Phoney reflected
opinion they are in a brotherhood of genuine Christians, a paradise on Earth and ark of salvation. Their "accurate knowledge" isn't genuine intellectuality, it is primitive because they must function with the approval of their Witch Doctor.
I suggest that many Jehovah's Witnesses are caught in a cognitive loop. They are convinced the source is infallible and therefore must be followed without question. To question the "infallible" source causes great discomfort, becuase the implication is that their entire philosophical foundation is flawed. It is much more logical to assume that they are somehow imperfectly following the instructions. So they try harder. This is all logical and reasonable to the person caught in the loop. Unless, of course, they are blessed by an new, external observation. This is how an "intellectual" may be caught, successfully, by the Witness philosophy. All very logical and reasonable.
Your personal philosophy is your software program that runs all your applications. For a philosophy to benefit you it must be workable: it must have practical applications in your daily life. You must come out ahead. You must prosper. Otherwise, your strategy is wrong.
I have come very close to following this criteria, myself. But I don't think it is the only workable philosophy. Very many people value personal relationships over honesty. Their philosophy, though at comes at great personal cost, is also valuable.
