“If E1 is the cause of E2, then a small variation (a mark) in E1 is associated with a small variation in E2, whereas small variations in E2 are not associated with variations in E1. If we wish to express even more clearly that this concept does not contain the concept of temporal order, we can express it in the following form, where events that show a slight variation are designated E: E1E2, E1E2, E1E2 and never the combination E1*E2.”

“…introduce the auxiliary concept of first-signal…defined as the fastest message carrier between any two points in space. We now send a first-signal from P, calling the event of departure E1… The event of its arrival at P' is called E'. Simultaneously with the arrival of this signal, another first signal is sent from P'. The arrival of this signal at P is the event E2. …the time interval between E1 and E2 is coordinated to the event E', [E1 is earlier than E' and E2 is later than E'] and every event of this time interval except for the endpoints is inderterminate as to the time order relative to E.”

“Evolution must have involved the simultaneous change in many genes, which doubtless accounts for its slowness. Here matters would have been easier if heritable variations really formed a continuum, as Darwin apparently thought, i. e. if there were no limit to the possible smallness of a variation. But this is clearly not the case when we are considering meristic characters. …the atomic nature of Mendelian inheritance suggests very strongly that even where variation is apparently continuous this appearance is deceptive.”

“I'm really interested in the harp as a fully actualized, self-contained way of presenting songs. That there is a bass in the harp - there is a way to create a rhythmic sense without drums - there's a way to have all sorts of textural variations and expressive variations.”

Joanna Newsom (1982) American musician

Sunday Service, 13 December 2004
Context: I'm not terribly interested in playing harp on other people's music right now. Partly because I feel like many people view the harp as this kind of gimmick. You know, like they have songs that are fully realized, complete songs, and then they think "How do we make this special? - Ooh, let's bring the harp in!" and they kind of want a harpist to play a glissando and play some heavenly noise in the background. I'm really interested in the harp as a fully actualized, self-contained way of presenting songs. That there is a bass in the harp - there is a way to create a rhythmic sense without drums - there's a way to have all sorts of textural variations and expressive variations.
I also don't want to feel bound to the harp, I'd be interested in bringing other instruments in at some time. But I think the harp has been viewed in one particular way for so long, and has been limited for so long, that I feel like I am really interested in stretching the boundaries of what it's capable of doing and how it's perceived.

“It's bullshit to think of friendship and romance as being different. They're not. They're just variations of the same love. Variations of the same desire to be close.”

Variant: It's b******* to think of friendship and romance being different. They're not. They're just variations of the same love. Variatons of the same desire to be close.
