No, not that kind -->
I'm thinking about the notion of "spirit" as used in the Bible, ancient and medieval religion as well as "superstition"... that which is common to "angels," "demons," "ghosts," "souls," the "Holy Spirit/Ghost" -- and even "God," at least according to the Fourth Gospel; that which underlies such widely different concepts as "spirituality," "spiritualism" or "spiritism".
It seems to me that by stepping into "modernity" we have shifted from a worldview in which the notion of "spirit" was taken for granted and ubiquitous to another in which it is no longer understood. The Johannine sentence "God is Spirit" sounds like explaining obscura per obscuriora. Tentative translations of "spirit" into modern speech -- whether of a philosophical kind as "principle," or of a scientific kind as "energy" -- do not appear to work very well. In practice, people seem to be required to either "believe in spirits" or dismiss them without a clue about what a spirit actually is (or might be).
My question is not whether you believe in "spirits" or not -- not even why. It is, rather, about what you understand by that word -- if anything. And, second, about the consequences of the general loss of that concept on the modern world in general and its religion in particular. Are we missing something in our approach to reality? Can religion, or "spirituality," do without such a basic notion?
