“...if I do not take my intellectual vocation seriously, putting it before everything else even at the risk of appearing inhuman, then I am also incapable of helping people in more concrete and proximate ways. Conversely, if I am not alert and ready to save people from a conflagration, that is to say, if I do not take my spiritual calling in all earnestness, sacrificing to it all else, even my own life, then I shall be unable to help in rescuing the manuscript. If I do not involve myself in the concrete issues of my time, and if I do not open my house to all the winds of the world, then anything I produce from an ivory tower will be barren and cursed. Yet if I do not shut doors and windows in order to concentrate on this work, then I will not be able to offer anything of value to my neighbors.”
