Can I be told what is meant by this sentence in some other way?

X falls into the same essence that is at the heart of Y. (Source)

( What is meant by "to fall into the same essence" and "the essence that's at the heart of something" )

[[ The paragraph which the sentence is located in the main text: (it's technical though)

Physical protection of any facility maintains the same fundamental requirements: You perform a threat analysis of your site, then you design a system that involves equipment and procedures, and finally you test it for adaptation. The system itself typically has a number of elements that fall into the same essence that is at the heart of protection: deter–detect–delay–respond. ]]

  • I agree that more context is needed. At the moment, it's very hard to tell what this sentence means and it looks like rather bad writing. Commented Aug 20, 2016 at 13:37

    Your text is either from a non-native speaker or it's someone with limited language skills unsuccessfully trying to use a register he's not very familiar with. Almost certainly what he's trying to say is something along the lines of There is a characteristic which is central to Y (i.e. - it's the essence of Y, at the heart of Y), and X has that same characteristic (i.e. - it falls into the same category as Y).

    You can paraphrase it so: A fourfold strategy is at the heart of any system which is designed to protect: deter, detect, delay, and respond.

1 Answer 1


The author is saying there are four considerations at the heart of "protection" (in general)


He goes on to say that the design and evaluation of a protection plan ("X") for a physical asset, e.g. a building or a castle, needs to take into account ("fall into") these four essential criteria ("the essence").
