On 10 April 2024 the Teatro Liceo in Salamanca hosted the first tribute «Salamanca por Cajal y la Ciencia». The papers from that day were meant to become a volume that was never printed. Amicus Certus now publishes it: twenty-nine chapters by physicians, lawyers, neuroscientists, engineers, psychologists and histologists looking at Santiago Ramón y Cajal from their own trade, and the Salamanca Declaration for Science, issued that same day. The book is in Spanish.

It is neither a biography nor a neuroscience book, but a many-handed portrait of the man who taught us to look at the brain. Edited by José Francisco Adserias Vistué; cover illustration by Antonio Diu.

The complete digital edition is a free download on the book page. The paperback (€9.99) and the Kindle eBook (€4.99) will be on Amazon in the coming days.

Amicus Certus publishes in English three studies by Ricardo Rivero Ortega, Professor of Administrative Law and former Rector of the University of Salamanca:

• “The Obligation. Regulation of Public Duties” (162 pages): what the law may demand of citizens, and how duties are regulated.
• “Law and Artificial Intelligence. Four Studies” (78 pages): four studies on what artificial intelligence changes for the law.
• “Law and Human Evolution” (88 pages): the law seen in the light of human evolution.

The three books form the Ricardo Rivero Ortega: Law Collection on Amazon (paperback from €9.99, Kindle €4.99). Two short essays complete the picture, each in Spanish and in English and priced at €2.99 on Kindle: Paradoxes of Subjective Social Rights and The Influence of the School of Salamanca on the Declaration of Independence and the Constitution of the United States.

Knowing the law takes more than knowing statutes. On that idea José Ramón Chaves García builds a wide-ranging essay on legal epistemology — what the jurist knows, how, and the part conscience and justice play in that knowledge — with a foreword by the neuroscientist José Ramón Alonso and a cover illustration by José Manuel Esteban Guijarro. The book is in Spanish; an Italian edition is also available.
