No, it’s not, contrary to the sentimental meme. Reading or hearing the sappier assurances that all you need is love triggers my gag reflex. For example, as quoted in Chris Hedges’ recent article, "Acts of Love," even the existential psychologist Viktor Frankl rhapsodizes “that love is the ultimate and the highest goal to which man can aspire,” that “the meaning of the greatest secret that human poetry and human thought and belief have to impart” is that “The salvation of man is through love and in love.” Luckily, Chris Hedges' defense of the meme is slightly more readable, so I'll summarize and discuss his article to elucidate why love is not our highest good after all, contrary to popular opinion.
Chris Hedges on Love
Hedges summarizes his view of why love is so great:
Love, the deepest human commitment, the force that defies empirical examination and yet is the defining and most glorious element in human life, the love between two people, between children and parents, between friends, between partners, reminds us of why we have been created for our brief sojourns on the planet. Those who cannot love--and I have seen these deformed human beings in the wars and conflicts I covered--are spiritually and emotionally dead. They affirm themselves through destruction, first of others and then, finally, of themselves. Those incapable of love never live.
According to Hedges, love is opposed to loneliness, which is the “most acute form of human suffering.” As he explains, “The isolated human individual can never be fully human. And for those cut off from others, for those alienated from the world around them, the false covenants of race, nationalism, the glorious cause, class and gender compete, with great seduction, against the covenant of love.”
