The Quest for Guidance
• Franz Kafka's "An Imperial Message"
illustrates the human search for guidance
and meaning.
• A dying king sends a message, but it faces
obstacles and distance, symbolizing the
challenges of finding one's way.
• The reader waits, hoping for guidance,
reflecting our own quest for moral
direction.
If early morning tomorrow you wake
up so sure that there is no God,
what would you do?
Immanuel Kant (1724-1804) proposed
a viable human solution to this
quandary.
His philosophy views man as
autonomous and most of him- or
herself as not subject to external
conditions, results, and mandates.
His philosophy views man as autonomous
If left to him or herself, is
it possible for the human
person to be ethical?
Immanuel Kant thinks so.
Kant's ethics are independent of religion
Kant's Ethics and Religion
Ethics: Based on reason, not external authority
Autonomy: self-legislated laws
Focus on duty: categorical imperative
Religion:
• Not the foundation of morality
• Morality leads to religion (pursuit of highest good)
• Moral religion: based on reason and morality
"Two things fill the mind with ever new and increasing admiration
and awe... the ember in the stars and the moral law within."

Kant's Ethics
• Foundation: Autonomous Reason
• Source: Goodwill
• Motivation: Duty
Key Point: Ethics should be based on
autonomous reason, not external authority.
Autonomous Reason, Goodwill, and Duty
Kant's Ethics:
• Man as an end in himself
• Autonomous reason - Be accountable to other
reasonable beings
• Universalizable obligation - Treat others as ends in
themselves
Kant's Ethics and Religion:
• Ethics is independent of religion
• Duty is motivated by reason and
goodwill
• Happiness is a gift, not a motivation
for ethics
Ethics and Hope:
• Ethics leads to hope for happiness
• Happiness is a gratuitous gift that one
cannot give to oneself
"Act in such a way that
you treat humanity,
whether in your own
person or in the person
of any other, never
merely as a means to an
end, but always at the
same time as an end,"
Conclusion
Kant's ethics provided for a ground for legislating norms
of rational behavior for autonomous persons. His ethical
system emerged at a time when Western civilization sought
a foundation for moral behavior that did not depend on
faith or tradition. Kant provided that and in effect gave the
justification and possibility for reason being the sole ground
for determining the good.
