Hi, what's an example of an interconnection between a musical structure and psychological development?

To believe that everyone in heaven is white undermines the relevance of skin-colour (including white); for then we're basically all the same. It seem fairly compatible with being against racism.

When we achieve an elevation in understanding, there is great satisfaction, no? The same could be said about achieving mastery in the arts, or even athletic pursuits. . . . — John

Right. A cliff-diver who learns a new dive may find the height and the risks involved unpleasant, but overcoming the fear and mastering the dive very pleasant. These experiences tend to dwindle, however, as the dive becomes a habit. But then there is typically a new, more difficult dive, to learn. :)

But the ability to overcome unpleasant experiences becomes controversial in cases such as medical experiments on animals, or uses of violence or torture on humans. Humans have many ways to psychologically rationalize the most horrific acts, to make them seem tolerable, or admirable, which in turn may evoke pleasure even. :(

The market is the exchange of goods and services for money, which includes the process of establishing their prices.

But often in comments and interviews on economy on the news, for instance, 'the market' seems comparable to a medieval use of 'God'. Instead of priests telling us about 'God's will' there are economists or the like telling us what 'the market' demands, or else we will perish. The market is referred to as if it would be an omnipresent creature with its own inscrutable logic.

Interesting stuff, but I don't get how pleasure and pain could be attitudes towards experiences. How could one possibly identify an experience at all, as an experience, if the pain or pleasure is not the experience but an attitude towards it?

For example, a painful pinch in my arm may evoke conscious awareness of the fact that my body behaves as it should, which in turn may evoke pleasure. The pinch being the cause of the pain, awareness of a working body being the cause of the pleasure.

Promises of the internet:
1) liberating technology provide decentralized networks, community-developed software and services.
2) cosmopolitanism, education accessible for all, fair competition based on merit and not heritage.
3) the possibility to publish and discuss topics incognito, or to critique power without risking punishment.
4) an alternative or parallel "world" open for exploration, inspiring creativity in a variety of fields.

Disappointments of the internet:
1) Private corporations provide centralized social networks, and exploit users' privacy as a product.
2) Marketing and bigotry thrive on easy and fast online distribution more than anything with content.
3) Unmoderated fora enable bullies to get away with persecution.
4) A world replete with creative works, freely available by file-sharing, might demotivate creativity.

Most sea urchins have no brains, nor eyes, yet they behave as if they would be somehow aware of themselves, their environment, and of ways to hide from predators. The entire body seems to function as a "compound eye".

The physical nature of the material or medium is nowadays typically a domain for structural engineers, not architects. In a lot of contemporary architecture imagery (e.g. printed textures, patterns, pictures) seems to have a lot more significance than the nature of the material or medium.
