My book is finally out and available at Routledge.
Hope it adds (even just a little!) to our understanding of early medieval philosophy and mathematics.

Mathematics and Philosophy at the Turn of the First Millennium: Abbo of Fleury on Calculus

At the turn of the first millennium, scientific and philosophical knowledge was far from dormant. Arithmetic, with its diverse calculation techniques and number theory, served as a bridge to philosoph...

Congrats to new PhD Silvia Cerasaro, who last week defended her thesis at the Dept. of Mathematics, Tor Vergata (Rome)! She showed how history of math can support math teaching in primary school. Fibonacci on fractions was her case study. I advised her on the medieval side of the project.

Do you need help with medieval Latin? I offer language teaching *and* research assistance, so if you just want a quick answer – e.g. a transcription or translation, or a manuscript identification – I can do that too. Further details here: latin.brunellus.com #medievalLatin #medievalSky

After all, like Federspiel said in one of his articles
« la droite euclidienne est devenue, en tant que droite, un être mathématique au contenu intuitif extrêmement pauvre, pour ne pas dire nul – aussi nul, peut-être, que celui du schmilblic hilbertien ».

And it wouldn’t’ surprise me if no particular thinker before modernity felt the need to emend this definition in this direction. 🤷‍♀️

Clelia Crialesi @cleliacrialesi.bsky.social · Feb 19

But again, your 1st option sounds safe enough to me, for it doesn’t seem that since Euclid, the definition of the straight line has included specific references to features like non-bent, non-angled, etc.

Clelia Crialesi @cleliacrialesi.bsky.social · Feb 19

But I can’t claim to know all the instances and shades of 'straight', neither in geometry nor in other fields.

Clelia Crialesi @cleliacrialesi.bsky.social · Feb 19

Sorry for the delay, I wanted to take some time to think about it. If I had to choose, I'd go with the first option (the intrinsic or positive one, as you put it), at least when 'straight' applies to a geometric entity like the line.
