I became aware of a voice inside my head. [...] It was only later that I realized that this voice was my own thinking, that this moment of anguish was my first inkling that I was a ceaseless monologue trapped within myself. - Yann Martel
I owe my first inkling of the problem of infinity to a large biscuit tin that was a source of vertiginous mystery during my childhood. - Jorge Luis Borges
