Lyric discussion by millivanilliscoop 

To me, this song is about the way things fall apart under the touch of "cold philosophy", our worry, over-analysis, and need to deconstruct everything - the butcher in our brains. Here's a portion of Lamia by John Keats which summarizes the kind of emotion I think this song is talking about:

"Do not all charms fly At the mere touch of cold philosophy? 
There was an awful rainbow once in heaven:
 We know her woof, her texture; she is given 
In the dull catalogue of common things.
 Philosophy will clip an Angel's wings, 
Conquer all mysteries by rule and line,
 Empty the haunted air, and gnomed mine
 Unweave a rainbow, as it erewhile made The tender-person'd Lamia melt into a shade."

The song is about looking back on your life, realizing you have been a butcher to the tender, important things in life, and have grown lonely, unable to feel much of anything because of it. Perhaps you have become this way because you feared "beauty will destroy your mind". I'm not sure what "gift wrap for the man with everything" means, but perhaps the "gift wrap" is the philosophy, the summary, the container, the "dull catalogue of common things" as the poem puts it. Yet your "heart's still pumping", you wish to overcome this critical part of your thoughts.
