Before Dracula there was Carmilla, the Sapphic vampire tale of a young girl who discovers her friend is more than a friend, in more ways that one. Despite being Victorian, Le Fanu's novella never antagonizes homosexuality. #FairytaleTuesday

🖼: D.H. Friston

A scene from Carmilla illustrated by D.H. Friston, showing the namesake vampire reaching across the bed to Bertha, who sleeps sprawled across her bed with one of her breasts semi-exposed seductively (for the viewer and for Carmilla, male gaze at work here folks). General Spielsdorf, sword out, is ready to attack Carmilla in her beastly form, and is emerging from a closet. Lots to read into this picture, folks.

Who's excited about leafy autumn trails?

With over 3,300km of footpaths, bridleways and byways, there's loads of great opportunities to make the most of the Autumn.

Check out some of our suggested walking routes 👉 www.southdowns.gov.uk/get-active/south-downs-walks

A photo looking upwards underneath Bonnet fungi with grey stems and cream tops. The stems are attached to the wood with numerous hyphae that look like cream fluff.

A few lovelies from Friston Forest, Sussex, today - Tan Ear, Crested Coral, Porcelain fungus, and last, but definitely not least, the beautiful Saffrondrop Bonnet #FungiFriends #fungi

The Tan Ear fungus that looks like a scroll of brown paper. The outside is cream and the inside is much darker brown. The fungi is set among twigs and brown leaves

Crested Coral fungus that consists of numerous white/cream stems rising from dead leaves of the wood floor. The ends of the fungus are split giving them a feathery look.

Porcelain fungus sprouting from a rotten log. Four white shiny fungi have cream stems. The tops of the fungi look almost wet due to mucus on them.

Saffrondrop Bonnet with a delicate narrow orange stem and a yellow/orange cap. The fungus is growing from the wood floor of twigs and dead leaves.

@neurograce.bsky.social

Tbf I think these are reasonable defenses & the author's rebuttal seems to conflate mechanistic and normative questions. If you want to know *why* a system is the way it is, a mechanistic (dynamical systems) model of the system as it is isn't going to answer that. You have to look to something else

$6.4 Potential defenses of optimality frameworks 526 Proponents of optimality models in human movement science (and beyond) might counter these critiques by arguing 527 that optimization frameworks are intended as useful approximations rather than literal descriptions of biological 528 processes. They might contend that natural selection produces behaviors that approximate optimal solutions within 529 ecological contexts even if organisms do not explicitly compute optima (Alexander, 2003; Parker and Smith, 1990). 530 Some defenders emphasize that modern optimization approaches incorporate constraints, multi-objective functions, 531 and stochastic elements to address biological complexity (Seth and Friston, 2016; Todorov, 2004). Others might 532 argue that optimization provides valuable normative benchmarks against which to compare actual performance, even 533 if perfect optimization is not achieved. While these defenses have merit in specific contexts, they ultimately sidestep 534 the fundamental issue: optimization frameworks impose mathematical structures fundamentally incompatible with 535 biological systems’ fractal, historically contingent nature (Gould, 2002; West, 2006). Furthermore, if optimization is 536 merely metaphorical rather than mechanistic, its scientific value becomes questionable—especially when alternatives 537 like dynamical systems approaches offer metaphorical appeal and mathematical compatibility with biological reality 538 (Kelso, 1995; Thelen and Smith, 1994). Despite these limitations, the persistence of optimization models suggests 539 they function more as conceptual scaffolding for researchers than as accurate representations of biological processes 540 (Chemero, 2009; Lakoff and Johnson, 1999)$
