A selection from R. D. Laing’s Knots (1970). Here is another:
Mother loves me because she is good I am bad, to think she is bad therefore if I am good she is good and loves me because I am good to know she is good. I am bad to doubt she punishes me for doubting she loves me by punishing me for doubting she loves me. She says it must be her fault if I doubt she loves me. She feels bad because I don't think she loves me because she feels bad when I don't think she loves me. She feels it is her fault that I can be so cruel as to doubt she loves me when she makes me feel cruel, to think she tries to make me feel cruel.
Laing was a radical Scottish psychiatrist influenced by existential philosophy and the anti-psychiatry movement of the 1960’s. Not immune himself to mental illness, he suffered from depression and alcoholism.
