The principle that highlights the belief in finding solutions to human problems through reason and humanity aligns perfectly with the core tenets of humanism. Humanism is a philosophical stance that emphasizes the value and agency of human beings, focusing on the importance of rational thinking and ethical considerations grounded in human experiences rather than divine or supernatural revelations.

This concept promotes the idea that through critical thinking, empathy, and cooperation, individuals can understand and address the challenges in life without relying on external religious dogmas or sacred texts. Humanists advocate for using human reason to navigate moral dilemmas and improve the human condition, which explains why recognizing reason and humanity as essential tools for problem-solving is central to this philosophy.

The other options reflect beliefs associated with religious traditions or doctrines rather than humanist principles. For instance, founding moral values on sacred texts or claiming that scientific methods validate traditional religions do not embody the humanist focus on reason as a guiding principle. Likewise, talking about reincarnation suggests a spiritual framework more aligned with specific religious doctrines rather than the secular, human-centered viewpoint of humanism.
