the past, specifically with "Eight Miles High" and "5D (Fifth Dimension)", when the band finally did record a song unequivocally dealing with drugs it was largely ignored by journalists. "Artificial Energy" is followed on the album by the poignant and nostalgic Goffin–King song "Goin' Back". With its chiming 12-string Rickenbacker guitar and polished harmony singing, band biographer Johnny Rogan has described the song as providing a sharp contrast to the negativity and violence of the opening track. The song's lyrics describe an attempt on the part of the singer to reject the cynicism that comes with being an adult in favor of the innocence of childhood. Thematically, the song recalled the title of the Byrds' previous album, Younger Than Yesterday, and the understated pedal steel guitar playing of Red Rhodes gives the track a subtle country flavor. A second Goffin–King composition, "Wasn't Born to Follow", also displays country and western influences, albeit filtered through the band's psychedelic and garage rock tendencies. The song's country leanings are underscored by the criss-crossing musical dialogue between the electric guitar and pedal steel. The rural ambiance is further heightened by the striking imagery of the lyrics which outline the need for escape and independence: a subject perfectly in keeping with the hippie ethos of the day. Another song on the album that deals with the need to escape the confines of society is David Crosby's "Dolphin's Smile". The song was an early example of Crosby's penchant for using nautical imagery in his songs, a thematic trait he would utilize in future compositions, including "Wooden Ships" and "The Lee Shore". The theme of unfettered idyllic bliss is further explored in the Hillman-penned "Natural Harmony". Like "Goin' Back", "Natural Harmony" conveys a sense of longing for the innocence of youth, albeit filtered through the awareness-raising properties of psychedelic drugs. It has been suggested by some commentators that the song exhibits the strong influence of Crosby's writing style, with its laid-back, jazzy feel and dreamy, high tenor vocal part. The McGuinn and Hillman composition "Change Is Now", with its lyrics advising the listener to live life to the full, represents a celebration of the philosophy of carpe diem (popularly translated as "seize the day"). Within this context, the song's lyrics explored a number of other themes, including epiphenomenalism, communalism, and human ecology. The quasi-philosophical nature of the song prompted McGuinn to flippantly describe it in a 1969
