Plants were an essential part of medieval life. Most people lived in houses made of wood and thatch, which often accidentally burned down when they cooked their food or huddled over wood fires to keep warm. People wore linen clothing dyed with plants. They drank ale, cider and wine as they danced to music played on wooden instruments. Beauty, love and seduction could all be made easier with a few herbal preparations. If you became ill, plants provided many of the cures. The unwary may have mistaken a poisonous plant for one that was good to eat, with fatal consequence. Others may have used the poisonous plant to remove an unwanted rival. Some plants had magical properties. The mysterious mandrake could kill anybody who tried to dig it up without taking the appropriate precautions. Demons could be summoned or dismissed by the aid of plants. The church used powerful incense to clean the air and induce a sense of religious euphoria.

Philosophical Uses of Categoricity Arguments


Free Download Penelope Maddy, "Philosophical Uses of Categoricity Arguments "
English | ISBN: 1009467964 | 2023 | 75 pages | PDF | 2 MB
This Element addresses the viability of categoricity arguments in philosophy by focusing with some care on the specific conclusions that a sampling of prominent figures have attempted to draw – the same theorem might successfully support one such conclusion while failing to support another. It begins with Dedekind, Zermelo, and Kreisel, casting doubt on received readings of the latter two and highlighting the success of all three in achieving what are argued to be their actual goals. These earlier uses of categoricity arguments are then compared and contrasted with more recent work of Parsons and the co-authors Button and Walsh. Highlighting the roles of first- and second-order theorems, of external and internal theorems, the Element concludes that categoricity arguments have been more effective in historical cases that reflect philosophically on internal mathematical matters than in recent questions of pre-theoretic metaphysics.
