And Once Again . . . The Objective
The primary aim and overall objective, among other
subsidiary benefits, is to assist in familiarising and acquainting its recipients with the conceptual [and
intellectual] perils, predominantly encountered by religion in todays society, which are propelled by [or
in the name of] philosophy.
What is ‘Philosophy of Science’?
Some DefinitionsThe branch of
philosophy that is centered on a
critical examination of the
sciences: their methods and their
results
The investigation of questions that
arise from reflection upon
science and scientific practice
The discipline of philosophy of
science investigates how
scientific knowledge works – its goals and its
methods, its achievements and
its limitations
Questions Concerning Philosophy of Science
How is a scientific language
constructed?
What are the rules of correct
scientific reasoning?
What are the distinctive
features of a scientific
observation?
What is a scientific law, or
what does a scientific theory
consist of?
How are hypotheses and
theories empirically
tested?
What is achieved by
scientific explanation and
what is causality?
Most General Questions of
Philosophy of ScienceIs there an objective reality, and an objective truth?
• This lies on the border between philosophy of science and epistemology
What connection exists between science and value judgements?
• This lies on the border between philosophy of science and meta-ethics
Philosophy of Science is Divided into Two
Areas• Discusses the justification
and objectivity of scientific knowledge
• A central issue is the problem of induction
[1]Epistemology of Science
• Discusses philosophically puzzling aspects of the reality uncovered by science
• A central issue is the analysis of causation
[2]Metaphysics of Science
What is ‘Science’?
From the Latin ‘scientia’
[Knowledge]
At times science has been regarded as a part of philosophy,
and at others, separate from
philosophy
Sometimes looked upon as a single discipline, and at other times as a plural discipline
Sometimes it is regarded as having to
do with reality; the phenomena or the
appearances of things
The sciences are sometimes divided into deductive and inductive types, or
sciences of reason and sciences of fact
The Scientific Method
A set of procedures that scientists follow in order to gain knowledge about the world.
The scientific method is the process by which scientists, collectively and over time, endeavour to construct an
accurate (that is, reliable, consistent and non-arbitrary) representation of the world.

[1] Epistemology of Science
What is Induction?The process which
leads us from observations of
particular cases to universal
conclusions
Inference from a finite number of
particular cases to a further case or
to a general conclusion
Inductive Inferences
If a number of ravens have been observed, all of which are black
And if no raven has been
encountered that is not black
The inference to the conclusion that the next
observed raven will be black
Or the general conclusion that all ravens are
black
David Hume & the Problem of InductionThe rational basis of any such inference was challenged by
HumeHe believed that induction presupposed belief in the
uniformity of nature
but that this belief had no defence in
reason
and merely reflected a habit or custom of
the mind
David Hume & the Problem of Induction
Thus Hume suggests that the idea of necessity, essential to the
concepts of both causation and of natural law cannot be drawn from
our observation of the external world, but must instead be derived from the felt force of our habitual associations of “perceptions of the
mind”.
The Problem of Induction
‘All bodies fall with constant acceleration’
Such arguments are not logically
valid
The truth of the particular premises does not guarantee
the truth of the universal conclusion
That all bodies observed so
far have fallen with constant acceleration
does not guarantee that all future ones will do so too
One Response to the Problem of Induction
Popper’s Falsifiability
Science does not rely on induction in
the first place.
Rather it puts forward hypotheses
in a conjectural spirit, and then strives to refute
them.
Thus, as long as such hypotheses are falsifiable, in
the sense that there are possible observations that would disprove them, then the objectivity of
science is assured.
Critique of Popper’s Falsifiability
It offers no account of our entitlement to
believe in the truth of scientific theories,
rather than their falsity.
And so it fails to solve the problem of
induction.
Science Through the Eyes of Islam
Contrast Between Western & Islamic Approaches to ScienceWestern science is
atomised and manipulative in its
relationship to nature, since it does not see it as having any spiritual
meaning. It is just there to be used and
observed.
Islam encourages the view that the world is a
product of God, so a deeper reality lies behind it, and its
structure reveal to those who approach it
in the right way an inner meaning.
The Role of Science in Islam
All have a legitimate role to play in the scientific
enterprise of Islam. As long as Muslims are faithful to the
true spirit of Tawḥīd
Logical Thinking
Mathematical Analysis Observation/
Experimentation
The Role of a Muslim Scientist
A Muslim’s religious
consciousness influences his intellectual
attitude toward the reality and the study of it.
A Muslim knows that the physical world does not have
an independent existence of its
own.
The physical world, like all other worlds,
owes its existence to
God.
The spirit of Muslim observation and
experimentation is shaped by this religious consciousness.
Muslims carry out observations and
experimentations with the firm conviction that they are seeking to know an aspect
of the reality of God.
Scientific Methodology In Islam
Islamic science has always sought to apply different
methods in accordance with the nature of the
subject in question and modes of
understanding that subject.
Muslim scientists, in their cultivation and development
of the various sciences, have
relied upon every avenue of
knowledge open to man, from
ratiocination and interpretation of sacred scriptures
to observation and experimentation.
A Contrast in Methodologies
Modern Science
• Cannot retain its present epistemological foundation and adopt revealed scriptures along with intellectual intuition
• It would otherwise fall into a philosophical contradiction
Islam
• Adopts a Pluralistic methodology
• Possess a unified and coherent vision of what the multiplicity of methodologies mean

The Problem of Induction Introduced
by MuslimsIt provided an elaborate
explanation of God’s Omnipotence and His constant act of creation
It demonstrated the level of contingency of
the world and its phenomenon
It provided a metaphysical
understanding of the reality of the world
