Taken from his lectures in 1935. If true then, even more so now:

Martin Heidegger, German Philosopher, 1889 – 1976, An Introduction to Metaphysics

And yet there arises, in each epoch, individuals like yourself Karl, who encourage presence, stillness, reflection. People like the late John O’Donohue who encourage us to recognise the presence of our soul, remind us that the body is in the soul and not the other way around. Activists like Greta Thunberg who never give up … we have work to do. Namaste
Cheers Karl.
