In this lecture, Thierry Adda invites us to reconsider our relationship with the invisible, drawing inspiration from the wisdom of traditional civilisations. While our materialistic age tends to deny what escapes the senses, these ancient cultures perceived the invisible as a fully living and active reality.

In his view, symbols are bridges between the visible and the invisible, a universal language that gives access to a broader understanding of existence. They are not mere images, but mediators that connect us to a deeper dimension of reality.

Thierry Adda insists on the importance of reintegrating this symbolic vision into our modern lives, not to escape reality, but to give it new meaning. In a world in search of direction, reconnecting with symbols can calm existential angst and help us rediscover a form of inner responsibility: that of looking at the world from a higher vantage point, with a more open consciousness.

Finally, he reminds us that philosophy, far from being a mere intellectual exercise, can lead us to the gates of mystery. But this requires a twofold approach: disciplining the mind and, at the same time, purifying it, to allow the essential to be revealed.
