In memory of Professor Robert Lemba Tiebwa

The present Mélanges are in memory of Professor Robert Lemba Tiebwa. These friends and disciples have brought together texts to pay tribute to him and to reflect on his thought and the themes that were dear to him. The contributions in this book, edited by Chef de Travaux MUAMBA NGUESHE Tamis, are divided into two parts. The first is a collection of eulogies in honor of the illustrious departed, while the second is packed with scientific articles on his thought and field of research, or in any case texts that allude to him.
