I disagree. I've been reading Tarot for 35 years and have never used reversals. In my opinion if you truly understand the Tarot then reversals become just as pointless as the fabled celtic cross spread. IMO reversals are simply a new age thing invented to sell a few books.
The Pictorial Key to the Tarot was first published in 1911 and uses reversals. As near as I can tell from my research, the New Age as a "thing" had its beginning at Findhorn in Scotland in the very early 1960s. Waite must have gotten his idea from some even earlier source, unless he actually invented it (although, honestly, I don't find his reversed meanings of much use). I've been reading for 45 years now and have always used reversals, although I read them much less literally now than ever, more as a quick pointer to where I might want to look deeper than as a full-fledged interpretive tool.
