The consistency of the author describes many things about the fifteen themes in his book that human beings in life are still aware of their nature as intelligent animals. Pius Pandor explained the biographies and teachings of the great Greek philosophers, medieval, modern, and contemporary philosophers in order to specifically distinguish these themes, but the basic framework remains in Greek philosophers, especially Aristotle. The main purpose of this book is to take the reader slowly to understand and love philosophy. Understand and love philosophy with criticism and wisdom. Criticism means that philosophy is here to raise our awareness so as not to be carried away in the safe zone of life, but to dare to explore the dark alleys of life in a zone of challenge. While wisdom means that philosophy offers both depth and breadth of thinking horizons in the oceans of life.   Konsistensi penulis memaparkan banyak hal mengenai lima belas tema dalam bukunya bahwa manusia dalam hidup tetap menyadari kodaratnya sebagai binatang berakal budi. Pius Pandor memaparkan biografi serta ajaran para filsuf besar Yunani, filsuf abad pertengahan, modern, sampai dengan kontemporer untuk membedakan secara spesifik tema-tema itu, namun kerangka dasarnya tetap pada filsuf Yunani, terutama Aristoteles. Tujuan utama dari buku ini berusha untuk mengantar pembaca secara perlahan memahami dan mencintai filsafat. Memahami dan mencintai filsafat dengan kritik dan kebijaksanaan. Kritik berarti filsafat hadir untuk membangkitkan kesadaran kita agar tidak terhanyut dalam zona aman kehidupan, tetapi berani menelusuri lorong-lorong gelap kehidupan dalam zona tantangan. Sedangakan kebijaksanaan berarti filsafat menawarkan kedalaman sekaligus keluasan cakrawala berpikir dalam mengarungi samudera kehidupan.

Introduction: We tested whether a mechanical device (such as Hipsecure) to pinpoint the anterior pelvic plane (APP) as a guide can improve acetabular cup placement. To assess accuracy we asked: (1) is the APP an effective guide to position acetabular cup placement within acceptable ° of divergence from the optimal 40° inclination and 15° anteversion; (2) could a mechanical device increase the number of acetabular cup placements within Lewinnek’s safe zone (i.e. inclination 30° to 50°; anteversion 5° to 25°)? Methods: 16 cadaveric specimens were used to assess the 3D surgical success of using a mechanical device APP to guide acetabular cup placement along the APP. We used the Hipsecure mechanical device to implant acetabular cups at 40° inclination and 15° anteversion. Subequently, all cadaveric specimens with implants were scanned with a CT and 3D models were created of the pelvis and acetabular cups to assess the outcome in terms of Lewinnek’s safe zones. Results: The mean inclination of the 16 implants was 40.6° (95% CI, 37.7–43.4) and the mean anteversion angle was 13.4° (95% CI, 10.7–16.1). All 16 cup placements were within Lewinnek’s safe zone for inclination (between 30° and 50°) and all but 2 were within Lewinnek’s safe zone for anteversion (between 5° and 25°). Conclusion: In cadaveric specimens, the use of a mechanical device and the APP as a guide for acetabular cup placement resulted in good positioning with respect to both of Lewinnek’s safe zones.
