Prepositions

He (the non-native English speaker) wrote

Teachers and administrators are in the heart of this transition since they are directly responsible for implementing ICT in educational curricula.

I jumped to correct the ‘in the heart’ to ‘at the heart’.

And then I stopped, and thought, and commented to myself:

Interesting aspect of prepositional use .. why am I (21st century Australian) reluctant to say ‘in the heart’, as a metaphor for the critical/key role they play in this change?

Such a little thing, these prepositions.  Such a minor change?  But if we are talking, and thinking, about sociocultural aspects of change, perhaps there is more to it than that.
