In a compelling conversation, leadership expert Alexandre Havard discusses the 'three spiritual diseases'—rationalism, sentimentalism, and voluntarism—that can diminish our humanity. He shares insights on how these ideologies can separate our heart, mind, and will, leading us to live as 'partial human beings.' Havard warns against being swayed by influential thinkers like Descartes and Nietzsche, emphasizing the need for integration and emotional engagement for true personal growth in a fractured world.
