Hospitality itself, opens or is in advance open to someone who is neither expected nor invited

But pure or unconditional hospitality does not consist in such an invitation ("l invite you, l welcome you into my home, on the condition that you adapt to the laws and norms of my territory, according to my language, tradition, memory, and so on"). Pure and unconditional hospitality, hospitality itself, opens or is in advance open to someone who is neither expected nor invited, to whomever arrives as an absolutely foreign visitor, as a new arrival, nonidentifiable and unforeseeable, in short, wholly other. l would call this a hospitality of visitation rather than invitation. The visit might actually be very dangerous, and we must not ignore this fact, but would a hospitality without risk, a hospitality backed by certain assurances, a hospitality protected by an immune system against the wholly other, be true hospitality?
