overlap in meaning between a "trip" and travelling, resulting in narratives in which time and space become blurred. Where the songs do present as love songs, the authors continue, love is often conveyed as a unifying force among many, rather than between two individuals, or as a "way of life". Author and critic Kenneth Womack writes of the Beatles exploring "phenomenologies of consciousness" on Revolver, and he cites as examples "I'm Only Sleeping" preoccupation with dreams and the references to death in the lyrics to "Tomorrow Never Knows". In Womack's estimation, the songs represent two important elements of the human life cycle that are "philosophical opposites". Echoing this point, music critic Tim Riley writes that, just as "embracing life means accepting death", the fourteen tracks "link a disillusioned view of the modern world... with a belief in metaphysical transcendence". Philo finds the Beatles' "countercultural engagement" evident on even the songs that present as standard pop. In Reising's view, all the songs on Revolver are linked, in that each line in "Tomorrow Never Knows", the closing track, is alluded to or explored in the lyrics to one or more of the tracks that precede it. Side one "Taxman" Harrison wrote "Taxman" as a protest against the high marginal tax rates paid by top earners like the Beatles, which, under Harold Wilson's Labour government, amounted to 95 per cent of unearned income (i.e. interest on savings and investments) above the top threshold. The song's spoken count-in is out of tempo with the performance that follows, a device that Riley credits with establishing the "new studio aesthetic of Revolver". Harrison's vocals on the track were treated with heavy compression and ADT. In addition to playing a glissandi-inflected bass part reminiscent of Motown James Jamerson, McCartney performed the song's Indian-style guitar solo. The latter section was also edited onto the end of the original recording, ensuring that the track closed with the solo reprised over a fadeout. Rodriguez recognises "Taxman" as the first Beatles song written about "topical concerns"; he also cites its "abrasive sneer" as a precursor to the 1970s punk rock movement. Completed with input from Lennon, the lyrics refer by name to Wilson, who had just been re-elected as prime minister in the 1966 general election, and Edward Heath, the Conservative Leader of the Opposition. "Eleanor Rigby" Womack describes McCartney's "Eleanor Rigby" as a "narrative about the perils of loneliness". The
