Hospitality and hostility towards migrants and strangers are critical aspects of social interaction and community dynamics. Hospitality involves the welcoming and inclusive treatment of migrants and strangers, reflecting societal values of compassion, integration and cultural exchange. In contrast, hostility towards migrants and strangers manifest as negative attitudes, discrimination or even aggression. It can arise from fear, economic competition or cultural differences, leading to exclusionary practices, prejudice and social tensions. These dynamics profoundly impact migrants' experiences, influencing their integration into new societies and their overall well-being. By promoting hospitality and addressing hostility, societies can build inclusive environments that benefit both newcomers and host communities, promoting mutual understanding and collective prosperity. This book presents the complex subject of hospitality and hostility in the most comprehensible and easy to understand language. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. Through this book, we attempt to further enlighten the readers about the new concepts in this field.
