Critical thinking is a complex, dynamic process formed by attitudes and strategic skills, with the aim of achieving a specific goal or objective. The attitudes, including the critical thinking attitudes, constitute an important part of the idea of good care, of the good professional. It could be said that they become a virtue of the nursing profession. In this context, the ethics of virtue is a theoretical framework that becomes essential for analyse the critical thinking concept in nursing care and (...) nursing science. Because the ethics of virtue consider how cultivating virtues are necessary to understand and justify the decisions and guide the actions. Based on selective analysis of the descriptive and empirical literature that addresses conceptual review of critical thinking, we conducted an analysis of this topic in the settings of clinical practice, training and research from the virtue ethical framework. Following JBI critical appraisal checklist for text and opinion papers, we argue the need for critical thinking as an essential element for true excellence in care and that it should be encouraged among professionals. The importance of developing critical thinking skills in education is well substantiated; however, greater efforts are required to implement educational strategies directed at developing critical thinking in students and professionals undergoing training, along with measures that demonstrate their success. Lastly, we show that critical thinking constitutes a fundamental component in the research process, and can improve research competencies in nursing. We conclude that future research and actions must go further in the search for new evidence and open new horizons, to ensure a positive effect on clinical practice, patient health, student education and the growth of nursing science.
