Philosophy in action, podcasts

About Philosophy in Action

I’m Dr. Diana Brickell (formerly Diana Hsieh). I’m a philosopher, and I’ve long specialized in the application of rational principles to the challenges of real life. I completed my Ph.D in philosophy from the University of Colorado at Boulder in 2009. I retired from work as a public intellectual in 2015.

From September 2009 to September 2015, I produced a radio show and podcast, Philosophy in Action Radio. In the primary show, my co-host Greg Perkins and I answered questions applying rational principles to the challenges of real life. We broadcast live over the internet on Sunday mornings.

You can listen to these 362 podcasts by subscribing to the Podcast RSS Feed. You can also peruse the podcast archive, where episodes and questions are sorted by date and by topic.

My first book, Responsibility & Luck: A Defense of Praise and Blame, can be purchased in paperback and Kindle. The book defends the justice of moral praise and blame of persons using an Aristotelian theory of moral responsibility, thereby refuting Thomas Nagel’s “problem of moral luck.” My second book (and online course), Explore Atlas Shrugged, is a fantastic resource for anyone wishing to study Ayn Rand’s epic novel in depth.

Cambridge University, philosophy podcasts

The Faculty is part of the University’s School of Arts and Humanities.

There are over 30 academic philosophers working in the Faculty. We have about 150 undergraduates and about 50 graduate students.

The philosophical community in Cambridge is is enhanced by the presence of philosophers in other departments and Faculties – for example, Classics, History and Philosophy of Science, Law, Politics and International Studies. The Faculty of Philosophy has strong teaching and research links with these philosophers in the rest of the University.

Our undergraduate degree has a claim to be among the best single-subject philosophy degrees in the UK. Our postgraduate programmes have trained philosophers now working all over the world.

cellular automata

Un automa cellulare (dall’inglese Cellular automaton o Cellular automata, abbrev. CA) è un modello matematico usato per descrivere l’evoluzione di sistemi complessi discreti, studiati in teoria della computazione, matematica, fisica e biologia.

Un automa cellulare consiste di una griglia costituita da celle, per esempio un foglio a quadretti. La griglia può avere una qualunque dimensione finita; ogni porzione limitata di spazio deve contenere solo un numero finito di celle. Ciascuna di queste celle può assumere un insieme finito di stati (ad esempio, “vivo” o “morto”, un colore, una forma ecc.). Per ogni cella è necessario anche definire l’insieme delle celle che sono da considerare “vicine” alla cella data (ad esempio, nel caso di un foglio a quadretti, si possono definire “vicine” due celle adiacenti, oppure due celle distanti al massimo due quadretti). Ad un certo tempo t=0 si assegna ad ogni cella un determinato stato. L’insieme di questi stati costituisce lo stato iniziale dell’automa cellulare. Dopo un tempo prefissato ogni cella cambierà stato contemporaneamente a tutte le altre, secondo una regola fissata (che varia a seconda dell’automa cellulare preso in considerazione). Il modo in cui cambia stato una cella dipende solamente dal proprio stato attuale e dagli stati delle celle “vicine”. (Citazione da

What is Digital Philosophy?

Digital Philosophy (DP) is a new way of thinking about the fundamental workings of processes in nature. DP is an atomic theory carried to a logical extreme where all quantities in nature are finite and discrete. This means that, theoretically, any quantity can be represented exactly by an integer. Further, DP implies that nature harbors no infinities, infinitesimals, continuities, or locally determined random variables. This paper explores Digital Philosophy by examining the consequences of these premises.
