It is a dynamic _spiritual_ incest, more dangerous than sensual incest, because it is more intangible and less instinctively repugnant.

But let psychoanalysis fall into what discredit it may, it has done us this great service of proving to us that the intense upper sympathy, indeed the dynamic relation either of love-will or love-sympathy, between parent and child, upon the upper plane, inevitably involves us in a conclusion of incest.
For although it is our aim to establish a purely spiritual dynamic relation on the upper plane only, yet, because of the inevitable polarity of the human psychic system, we shall arouse at the same time a dynamic sensual activity on the lower plane, the deeper sensual plane.

We may be as pure as angels, and yet, being human, this will and must inevitably happen.

When Mrs.Ruskin said that John Ruskin should have married his mother she spoke the truth.

He _was_ married to his mother.
