The essays in this volume reflect on this and other subjects. The work is organised into four sections: 'The Soul and its Passions'; 'The Spheres of the Mind'; 'Flux and Stasis'; and 'More about the Phenomenon and its Unveiling'. Of especial significance are the opening essay by Tymieniecka entitled 'The Human Soul in the Metamorphosis of Life' and the last essay 'The Shared Quest Between Islamic Philosophy and Modern Phenomenology' by Reza Davari Ardkani. In her essay Tymieniecka sets out the bases for this dialogue by reflecting on concepts that are fundamental for knowledge (phenomenon, appearance, intuition) and on the position of man understood as a creative microcosm within the world. Encounter and dialogue with others, in faith, in religion, and in institutions, is the other side of the inquiry into rationality and the principle of human life to which philosophy has always dedicated itself. In his essay Reza Davari Ardekani, the President of the Academy of Sciences of the Islamic Republic of Iran, enucleates five subjects which can be adopted by Islamic phenomenologists and philosophers as a point of departure for a profound cultural dialogue and a contribution to the debate that is underway in contemporary culture. The first subject for shared reflection is intentionality (to which, however, Islamic philosophy, has not hitherto paid great attention); the second subject is the nexus between two forms of knowledge: that specific to daily life and that which is authentically philosophical. Other elements for reflection whose exploration could be especially fruitful, taking into account as well the fact that both phenomenology and Islamic philosophy ask themselves first and foremost about essences, are the place of historicity in philosophical knowledge and human knowledge and the distinction between perception and apperception, which is explored by phenomenology and by the important Persian philosopher Mulla Sadra (1571-1640) and taken as a term of dialogue in many essays. Lastly, the author calls for the restoration of Sophia Perennis at the centre of the debate, a classic subject which re-emerged in the thought of Husserl on the crisis of science and the destiny of philosophy, a subject that is dear to Islamic philosophy.
