Christians espouse various moral teachings, such as:
Blessed are the poor and humble.
Easier for a camel to pass through the eye of a needle than for a rich man to enter the kingdom of heaven.
Judge not, lest ye be judged.
Love thy neighbor as thyself.
If someone takes your cloak, give him your coat also.
Take no thought for the morrow.
To be perfect, sell all you have and give to the poor.
Although Christians express belief in these doctrines, Mill argues there is often a gap between belief and practice.
They believe to the extent of social convenience and personal behavior norms.
Doctrines may serve as tools for justification rather than genuine conviction.
Early Christians displayed a stronger adherence to these principles, facilitating the religion's expansion.
Their love and communal support for one another made a notable impression on outsiders.
Unlike today, the tenets were lived out with deep conviction.
Mill suggests the primary reason for Christianity's stagnation in modern times is the lack of genuine adherence to its moral maxims.
Mill discusses the risk individuals face when acting upon doctrines without deep understanding—often, these are merely accepted as truisms.
Many truths go unexamined and are often realized only through painful personal experience.
The challenge lies in the tendency for people to stop questioning once an opinion is widely accepted or assumed true.
Controversy is a vital component of intellectual evolution.
Lack of dissent leads to stagnation in understanding and belief.
First, silenced opinions might be true, leading to potential infallibility in the dominant view.
Second, the majority opinion often lacks the whole truth, and dissent can reveal these gaps.
Every doctrine's meaning can be lost if it is not continually debated.
Mill advocates reintroducing a method of debate similar to the Socratic dialogues to encourage critical thinking in education.
Presently, there is a lack of structured controversies in education, leading to complacency among learners.
Diversity in opinion allows for a more rounded comprehension of truths, as competing ideas often highlight different aspects of reality.
Mill affirms that significant advancements occur through understanding the full context, including minority opinions.
There is a need for dialogue that embraces diverse perspectives—not merely a submission of one accepted truth over another.
Effective discourse often requires a balance of contrasting views, which keeps individual beliefs dynamic and evolving.
Without the challenge from dissenting views, dominant opinions may devolve into dogmatism.
Mill concludes that for humanity to thrive, intellectual debate must remain uncurbed.
The true value of an opinion is only realized when it is contested and examined thoroughly.
Mill critiques Christian morality and its development through history.
He argues it is incomplete and too often reacted to the cultures of the time, leading to a lack of proactive moral structures.
Criticism of established doctrine is necessary for moral growth, asserting that moral systems should not suppress unorthodox approaches to ethics.
Additionally, modern interpretations of Christianity have been largely reactionary rather than actively progressive, often compromising deeper moral truths.
