    adjusted the Idea-paragraph

    in particular I added a line that VV-strong functors make sense between VV-tensored VV-enriched categories

    and hence deleted this sentence further down:

    The first thing to notice about (covariant) tensorial strengths is that they attach to a functor from a monoidal category to itself, say T:VVT: V \to V. (The concept doesn’t make much immediate sense if TT is a functor between different monoidal categories.)

    added pointer to:

    Added the warning (here) that Kock 1972 said “strong functor” for “enriched functor”

    I have given the paragraphs alluding to some work by C. S. Peirce an Examples-environment (here) but it remains a little mysterious without further details or references.

    In the course of this, I have taken the liberty of deleting this lead-in paragraph:

    There’s rather a lot more one could say about strengths, and I may come back to more of that later, but I would like to say that strengths are kind of a trade secret. The first mathematician I know of who intuitively grasped strength was C.S. Peirce!
