Subconsciousness

This is an actual photo of an iceberg. This came from a rig manager for Global Marine Drilling in St. Johns, Newfoundland. They actually have to divert the path of these things away from the rig by towing them with ships! Anyway, in this particular case the water was calm & the sun was almost directly overhead so that the diver was able to get into the water and take this picture. They estimated the weight at 300,000,000 tons.

最近在紐西蘭海上飄呀飄的冰山一角 (A43)，讓我對於意識是什麼的好奇又再度浮上了心頭。不過這個冰塊也飄了六年，從南極一路飄到紐西蘭...如果可以住在上面...那會是個怎麼樣的體驗？

In psychoanalytic theory, the unconscious refers to that part of mental functioning of which subjects make themselves unaware. The psychoanalytic unconscious is similar to but not precisely the same as the popular notion of the subconscious. However, in the modern field of personal development the terms 'unconscious mind' and 'subconscious mind' are often interchangeable.

For psychoanalysis, the unconscious does not include all of what is simply not conscious — it does not include e.g. motor skills — but rather, only what is actively repressed from conscious thought.

As defined by Sigmund Freud, the psyche is composed of different levels of consciousness, often defined in three parts as

• the preconscious
• the waking consciousness
• and beneath both of these, the unconscious.
