Kant believed that using his set of
statements based on morality one
could postulate the existence of God
Statement 1: A moral action
involves doing one's duty
Statement 2: You do your duty in
order to reach the Summum Bonum
S3: We cannot reach the Summum Bonum in our lifetimes
S4: The Summum Bonum must be
achievable
S 5: What makes it achievable?
Answer: God
Thus we must postulate the existence of God
Criticisms
Kant's argument is self contradictory. If we should not
do our duty to reach an end, then surely then
concept of the Summum Bonum, which is a reward
for doing your duty, contradicts this.
The power and knowledge to make the
Summum Bonum doesn't necessarily equate
to omnipotence and omniscience
Freud believed religion is a neurosis - a problem
experience repressed by the mind instead of
being solved - stems from a desire to have
protection and purpose.
If this is true the kant's
argument is illogical
Brian Davies
Kant assumes that only God can bring about
the summum bonum but it could equally be
brought about by a 'pantheon of angels.'
J.L. Mackie
Metaphysical
argument
In the metaphysical part of the argument
from queerness, Mackie argues that
objective values, including objective moral
values, do not exist because they are
metaphysically anomalous. He writes, “If
there were objective values, then they would
be entities or qualities or relations of a very
strange sort, utterly different from anything
else in the universe.”
Epistomology argument
There would be no way to know these queer things without
a special, non-empirical means of knowing them (intuition).
The central idea of intuitionism, which is that there is some
specific and unique interface with which humans come to
realize objective moral values, is thus the logical reduction
of all theories of objective values. At some point in these
theories, some essential concept or inference will only be
known via intuition, thus committing any consistent
objectivist theory to a “lame answer” to this problem.
Critique
He makes two implicit
assumptions about objective
moral theories
First, that if they are to have
objective values, that these
values must have an
existence in reality as objects
or relations have existence
Second, that knowledge
of such objective values
compels the agent to
comply.
Guilty of a straw-man fallacy
Misrepresenting an argument
to make it easier to criticise
The actual shortcoming of Mackie’s
argument is much more subtle: he is
essentially claiming that all objective moral
theories must possess these properties.
Sigmund Freud
The Oedipus complex is
the origin of morality
A child's sexual desire for the parent
Freud's model of the mind
Id = selfish animalistic
desire
Ego = reason and
thought
Super ego = the conscience
The Id desires the parent of the opposite gender and
want to kill the other parent, but the ego tells the child
not to act on desires because it will bring them into
conflict with the other parent who is bigger and stronger
The child knows its desires are wrong so it develops a feeling of
guilt and thus begins to develop a conscience, a superego
Eventually it learns to identify with the
parent of its own so this stage of child's
life ends and it develops a morality
If this is right then it proves that Kant's moral theory fails
Criticism
Lacks scientific evidence
Modern science does not support
the id/ego/superego model
Freud's theoretical models arise from a homogeneous sample
group—almost exclusively upper-class Austrian women living in the
sexually repressed society of the late 19th cent. Such a sample, many
psychologists contend, made Freud's focus on sex as a determinant of
personality too emphatic.
A number of modern psychologists have pointed out that
traditional psychoanalysis relies too much on ambiguities for its
data, such as dreams and free associations. Without empirical
evidence, Freudian theories often seem weak, and ultimately fail
to initiate standards for treatment.
Cardinal Newman
“We feel responsibility, are ashamed, are frightened at
transgressing the voice of conscience, this implies that there
is one to whom we are responsible." For Newman, the
existence of conscience implies a moral law-giver whom we
are answerable to – God.
C.S Lewis
There must be a moral law
or there would be no reason
to keep promises etc.
It can't be herd instinct as
sometimes we go against the
majority
Its not the law of nature as
sometimes what is best for
survival isn't morally right
Can't be the imagination as
everyone seems to have an
understanding of morality
Morality must come
from the mind as it can't
come from matter
And since it doesn't
come from humans it
must come from God
The argument doesnt work if
you dont accept that there
are moral absolutes
