Good quote, but, it's misleading. Note in the first sentence that "there are still fundamental disagreements within psychology about the nature of the subconscious mind". Sure, definitely. But the BRACKETED COMMENT "(if indeed it is considered to exist at all)" is ambiguous not only in meaning, but ALSO it is likely an addition of the person writing the Wikipedia entry rather than the sources he is working from, if any at all.
The moral of the story? Don't trust Wikipedia, it's frequently inaccurate, often misleading, and we know nothing about which anonymous contributors actually write the entries.
ON THE OTHER HAND, the Oxford English Dictionary defines subconscious (noun) as:
"The part of the mind which influences actions etc. without one's full awareness."
Now while I can certainly accept that it may not be absolutely certain the full nature and function of the human subconscious, it is ABSOLUTELY proven to exist. Examples:
- Our breathing is regulated and controlled without our being fully aware of this process of controlling, unless we pay conscious attention to it.
- When we are sitting in a room with multiple conversations and only paying attention to one (this is called the "cocktail party effect") we cannot consciously hear what is being said in conversations other than the one our attention is directed at, but yet if somebody in one of these "unattended" conversations mentions our name, our mind will register this, EVEN THOUGH we are not paying conscious attention to the conversation, and we will notice it and our attention will switch to that conversation.
- Blinking. Unless we consciously attempt to control blinking, it is regulated on a subconscious level.
- Depth perception. We are not conscious of the visual cues and system of processing that our mind uses to perceive depth, but we recognise the end result. All this "working out" happens behind the scenes on a subconscious level.
- Many, many, many more examples.
It is proven, as certain as the theory of gravity, that more goes on in our minds than we are conscious or aware of. This is, BY DEFINITION, the "subconscious". Though it's nature and function might be uncertain in some respects, it incontrovertably exists and is an important part of the human mind - I would argue, MUCH moreso than the conscious. We can live without being conscious - but we cannot live without our subconscious. The subconscious functioning that keeps our body alive is absolutely essential.
WIKIPEDIA IS WRONG
Point-blank, whoever wrote that entry is wrong. It's incorrect and misleading.
