L'amour et l'oubli
"Dormir avec une femme, ça peut être plus intime que faire l'amour. Ça implique un abandon, une confiance qui ne ressemble à rien d'autre. Cela, tu me l'as accordé. Pourrais-je jamais en être digne ? C'est alors que je suis le plus près de comprendre ce mot galvaudé qu'on a tant de mal à saisir : l'amour."

Air filtration: Do we have sufficient evidence to implement these air filtration equipment programs??
https://smartairfilters.com/en/blog/hepa-filter-release-dirty-particles-into-air/
The issue of air treatment in establishments open to the public is indeed closely linked to the risk of airborne propagation of micro-organisms and other pathogens. This question is not new since it has arisen and still arises in healthcare establishments, whether in the operating theatre or hospital departments and emergency rooms. The pandemic has led to reconsidering this issue of air treatment in addition to personal protection such as masks and social distancing.
1/ it is above all an economic question, the investments and operating costs are high, in particular for equipment with filtration or a virucidal or bactericidal device by UV, for example. Existing systems are rarely adaptable because the power of the air propulsion engines is insufficient. Operation assumes electrical consumption that has not been modelled for all of these buildings.
2/ The potential advantages are significant because they concern all pathologies linked to an agent transported by the air. These agents are numerous, infectious, allergic and toxic and their consequences on human health are fairly well documented. However, it is necessary to differentiate between short-term risks such as an influenza epidemic or a particularly important pollen episode and long-term risks such as particulate pollution... Large health databases make it possible to approach the economic benefit of such facilities.
3/ Solid evidence remains to be established. The number of randomized trials in this area is very limited. Public aid programs do not prejudge this evidence because the equipment is very varied in its effectiveness and cost. For example, portable devices for apartments can be efficient and inexpensive but what about schools (https://onlinelibrary.wiley.com/doi/10.1111/ina.13029)? Searching for randomized controlled trials with the title: "air filtration efficacy in respiratory infection" finds only 5 articles... This is why it is so important to obtain solid evidence before deciding on such expenditures. Public funds would be better used to improve this evidence, especially in real life, whether it concerns filtration methods in general but also devices in particular.

Quelques faits sur la question du Sionisme et de la politique étrangère du gouvernement français.
Les 3 raisons de l'hostilité française à l'égard d'Israël.
Popper and Truth
“But the approach to truth is not easy. There is only one way towards it, the way through error. Only through our errors can we learn; and only he will learn who is ready to appreciate and even to cherish the errors of others as stepping stones towards truth, and who searches for his own errors: who tries to find them, since only when he has become aware of them can he free himself from them.
The idea of our self-emancipation through knowledge is therefore not the same as the idea of our mastery over nature. The former is, rather, the idea of a spiritual self-liberation from error, from superstition and from false idols. It is the idea of one's own spiritual self-emancipation and growth, through one's own criticism of one's own ideas – though the help of others will always be needed.”
Karl Popper, 'In Search Of A Better World'.
