I came across some writing of the Finnish filmmaker and astrologer Altero Alli, from Portland, OR, reminding us of the well known, but easily forgotten, fact that biases shape all our experiences and perceptions. It is especially important for clients to keep this in mind. I quote (somewhat abbreviated):
"What precedes and underlies even the most skillful reading is something called bias. It should go without saying that all astrological interpretations reflect the subjective bias of the interpreter; the idiosyncratic filter of believes, ethics and values that an astrologer uses to interpret symbols and signs. There can be no such thing as ‘pure information’ or ‘absolute objective truths’ when interpreting an astrology chart. You can grow adamant and impassioned about your point of view (and you may even be right!) but it still remains your way of seeing."
