Personal Signs and Houses

The Personal signs and houses tend to be psychologically primitive and instinctual. They are me oriented. And they are ruled by the pleasure-pain mechanism. They are inclined to be somewhat simple and na??ve. In certain ways they can be childlike or childish. They may have blind spots, lacking the ability to have insight into their own or other??s motivations. They tend to believe automatically that everyone is like they are, or, if not, they should be. They are pre-moral in the sense that they lack awareness of others as separate and different egos, or selves. In extreme cases, this is the sociopath who can do correct behavior because he has learned what is expected and acceptable through observation. But there is no conscience, no inner motivation to do the right thing simply because it is the right thing (as a Universal sign would), or because of the awareness a Social sign would have: that to do otherwise might hurt someone, even himself.

The Personal signs and the corresponding houses are Aries, Taurus, Gemini, Cancer, and houses one through four.
