Raindrop shadows through my window / Clouds come and they go / Rain falls and drops descend / Impermanence again...


IMAGINE YOUR LIFE WITHOUT MEMORY. Knowledge, imprinted in your memory, is what defines you as a person. We would wander helplessly in the present without it. We owe our existence to our memory.

WHY IS THE STUDY OF HISTORY VITAL? History is memory on a global scale. It is the antidote that prevents the world from collective amnesia. Yet it is an antidote clouded and shaped by those who gaze upon the past. Without it, we understand nothing, with it, we understand imperfectly. Within that mystery lies the ever changing beauty in the pursuit of history.

Join me as we journey into the mists of the past together.
