That is not what the traditional logicians have in regard. (from a conversation with a teacher)
Possibilities. 1. “have in regard” here means “consider”. 2. It means “hold in respect”. 3. It is a wrong expression. Which one is closer to the truth?
The context is a discussion about Kant's transcendental logic: what is its characteristic, how is it different from the old logic, whether it is still related with in some way and even implied in modern logic. I think your explanation is right. Since the teacher who talked with me was not a native speaker, I just wonder whether it is good English.
