2. Who is Spinoza?
• Born in Amsterdam in 1632 to a Jewish Portuguese family
• Excluded from Amsterdam synagogue when 24
• Not a professional scholar
• Intellectual purity and radical perspective on various philosophical and
religious issues
• Rationalist, determinist European philosopher
• Ethics and Theologico-Political Treatise
4. Metaphysics
• Spinoza’s metaphysics consists of one thing, substance, and its
modifications (modes)
• In his book Ethics Spinoza argues that there is only one
substance, which is absolutely infinite, self-caused, and
eternal. he calls this substance “God", or “Nature“, in fact, he
takes these two terms to be synonymous ( the phrase he uses
is "deus sive natura")
5. Substance Modes and Attributes
• To the question "What is?" he replies: "Substance, its attributes, and modes“
• A substance "that which is in itself and is conceived through itself", meaning that it can be understood
without any reference to anything external
• A mode is something which cannot exist independently but rather must do so as part of something else on
which it depends, including properties (for example colour), relations (such as size) and individual things
• Modes can be further divided into 'finite' and 'infinite' ones
• Attribute is "that which the intellect perceives as constituting the essence of substance", and there are possibly
an infinite number of them. It is the essential nature which is "attributed" to reality by intellect
• God as "a substance consisting of infinite attributes, each of which expresses eternal and infinite essence",
and since "no cause or reason" can prevent such a being from existing, it therefore must exist
6. Propositions
• PROPOSITION 1: A substance is prior in nature to its affections.
• PROPOSITION 2: Two substances having different attributes have nothing in common with one another.
(In other words, if two substances differ in nature, then they have nothing in common).
• PROPOSITION 3: If things have nothing in common with one another, one of them cannot be the cause
of the other.
• PROPOSITION 4: Two or more distinct things are distinguished from one another, either by a difference
in the attributes [i.e., the natures or essences] of the substances or by a difference in their affections
[i.e., their accidental properties].
• PROPOSITION 5: In nature, there cannot be two or more substances of the same nature or attribute.
• PROPOSITION 6: One substance cannot be produced by another substance.
• PROPOSITION 7: It pertains to the nature of a substance to exist.
7. • PROPOSITION 8: Every substance is necessarily infinite.
• PROPOSITION 9: The more reality or being each thing has, the more attributes belong to it.
• PROPOSITION 10: Each attribute of a substance must be conceived through itself.
• PROPOSITION 11: God, or a substance consisting of infinite attributes, each of which expresses eternal
and infinite essence, necessarily exists. (The proof of this proposition consists simply in the classic
“ontological proof for God’s existence”. Spinoza writes that “if you deny this, conceive, if you can,
that God does not exist. Therefore, by axiom 7 [‘If a thing can be conceived as not existing, its
essence does not involve existence’], his essence does not involve existence. But this, by proposition
7, is absurd. Therefore, God necessarily exists, q.e.d.”)
• PROPOSITION 12: No attribute of a substance can be truly conceived from which it follows that the
substance can be divided.
• PROPOSITION 13: A substance which is absolutely infinite is indivisible.
• PROPOSITION 14: Except God, no substance can be or be conceived.
8. Classical Pantheism
"Whatever is, is in God, and nothing can exist or be conceived without God."
• This means that God is identical with the universe, an idea which he encapsulated in the phrase
"Deus sive Natura" ('God or Nature)
• Substances do not share attributes or essences and then Spinoza states that God is a "substance" with
an infinite number of attributes
• Therefore, God is just the sum of all the substances of the universe. God is the only substance in the
universe, and everything is a part of God
9. Anthropomorphism
• Rejected by Spinoza
• In scholium to proposition 15 he states that, “Those who feign God, like a man,
consisting of a body and a mind, and subject to passions. But how far they wander
from the true knowledge of God”
• God is not the underlying substance but more the sustaining cause of all things.
11. Epistemology
• Spinoza aimed to improve the intellectual abilities, in
order to overcome the doubts and confusions of
everyday perceptions.
• In his book “Treatise on the Emendation of intellect”
Spinoza taught to utilize the rational ability of the mind
to overcome the shackles of ignorance by the partial or
the inadequate knowledge
• Spinoza describes obtaining true knowledge as the sole
pathway to free oneself from the doubts and limitations
of the average human existence
• Spinoza imparts a realistic concept that true knowledge
does not guarantee monetary benefits or over the top
fame rather, it gifts us with the power of reasoning to
deal with everyday conundrums
12. Stoicism – As a power of true
knowledge
• Spinoza regards true knowledge as a gateway to stoicism
• True knowledge yields the power of rationality, which helps to derive logical
conclusions and make informed decisions
• The power of logical reasoning overshadows the vacillating emotions and feelings
generated by different problems faced in everyday life
• Reasoning tranquilizes or pacifies the unnecessary emotions that stem during difficult
situations and helps to make better decisions.
• Hence, according to Spinoza true knowledge inculcates within itself the philosophy of
stoicism
13. True Knowledge as a Path to
Blessedness
• Spinoza describes true blessedness as an expression of intellectual love towards an
infinite being.
• An emendation of intellect involves overcoming feelings and emotions and using
rationality to make decisions, become wise and discover the true laws on nature
• He views emendation as an avenue to improve oneself, by rewriting previously
held conventional notions through seeking true knowledge
• True knowledge would grant us an experience of the essence of all reality, which
is an experience that grants us freedom from finite concerns and pleasures and
endows us with true blessedness.
14. Methods for Spinoza’s Epistemology
• There are two methods for Spinoza's epistemology
1) Geometric Method
2) Perspectivism
1) Geometric Method
• Spinoza promotes a synthetic geometric approach, that involves the culmination of
axioms and principles that have already been proved as indubitable and infallible,
in order reach to other primary truths.
• This kind of technique allows one to build new knowledge which involves
proving propositions on the basis of previously established principles.
• Due to this reason Spinoza’s philosophy begins with God, the one substance that
composes everything. God and nature cannot be denied and form the basis from
which all other knowledge can be derived.
15. • To know adequately is to know the different ways knowledge can be known or
comprehended and the different ways knowledge knows things- which illuminates
the reflexivity of Spinoza’s epistemology
2) Perspectivism
• In this model Spinoza affirms substance monism by acknowledging the way humans
as well as all the beings can possess knowledge as to how God expresses himself in
everything
• Spinoza discusses that if all the ways of knowing are the ways God is known, then
through God’s perspective he knows himself in an infinity of ways such that our
finite and inadequate perspectives in our everyday lives are just so many of the
infinite ways God can know himself
• Spinoza advises that everyone must become as epistemologically self-reflective as
God is, so that we can become adequately aware of our inadequate knowledge.
16. Three Kinds of
Knowledge
• Spinoza describes three kinds of knowledge or kinds of
cognition. These are:
1) imagination
2) Intellect
3) intuition
17. First Kind of Knowledge: Imagination
• Spinoza regards imagination as the lowest level of knowledge
• Spinoza describes that affections in terms of the body encompasses the expression of receptivity,
reactivity etc.
• On the other hand, from the perspective of mind, affections tend to encompass the images of an affected
body
• However, Spinoza declares that knowledge based on images, affections constitutes a knowledge that is
partial and inadequate
• Prejudices and Superstitions
• Spinoza believed that the inadequate knowledge leads us towards prejudices as well as superstitions
• Miracles and Prophecies
• The inadequate knowledge resulting from imagination leads us to believe in miracles and prophecies
18. Second Kind of Knowledge: Intellect
• Spinoza says that in order to obtain adequate knowledge we must move past imagination and
should use the rational powers of intellect
• Spinoza explains that imagination is the way we think and perceive things usually.
• Spinoza elaborates that for a mind to be actively aware of it nature the mind must comprehend
the natural order it follows.
• Spinoza believes that once a finite intellect affirms or realizes that it is indeed a part of an
infinite intellect, it can improve or modify itself
• Reason
• Spinoza describes the power of “reason” as a power to pacify the reception towards the
affections.
• Through reasoning one can control his reaction towards the affections and keep his composure,
which will ultimately lead him to a powerful and strong person.
19. Third Kind of Knowledge: Intuition
• Intuitive knowledge has the potential to make us eternally wise and blessed
• It is rationality that prompts us to control our emotions and develop an adequate knowledge of
the world.
• Intuition allows us to not only know the attributes that we modify, rather we can know ourselves
as the attributes being modified along with other attributes that constitute the existence of God
• Love and Blessedness
• Intuitive knowledge paves the way to love and blessedness
• For the intellectual love of God the concept of “joy” resides internally rather than having an
external cause.
• The reason for this is that God is a part of our own existence, the joy associated
with intellectual love of God is acceptance of one’s own love for God’s perfectionism
• Intuition grants us “immortality”, in a sense that we live eternally by diverting our perspective
towards the infinite and eternal nature of God.
20. Panpsychism
• Panpsychism entails the concept of “universal mindedness”
• All the finite ideas as well as the finite minds, are a part of divine infinite intellect
• Human mind is a part of the infinite intellect of God. When it is said that the
human mind perceives God, it is so that God is explained through the nature of the
human mind
• Finite minds constitute the modes of an eternal substance, i.e God, as well as are a
part of the infinite intellect of God
22. Moral Anti-Realism
Moral Anti-Realism is a doctrine that moral
properties are mind-dependent, and there are no
objective moral qualities or normative values.
“For one and the same thing can, at the same time,
be good, and bad, and also indifferent. For
example, music is good for one who is melancholy,
bad for one who is mourning, and neither good nor
bad to one who is deaf” (E4pref).
23. Moral Anti-Realism
Every individual decides what is good for himself by
reason, and reason judges what is good for us.
“I shall understand by good…a means by which we
may approach nearer and nearer to the model of
human nature we set before ourselves. By evil,
what we certainly know prevents us from becoming
like that model” (E4pref)
24. Ethical Egoism
• Ethical Egoism states that an individual morally
ought to perform some action if and only if, and
because, performing that action maximizes
his/her self-interest.
• Based upon Conatus Doctrine:
“Each thing, as far as it can by its own power,
strives to persevere in its being” (E3p6)
25. Ethical Egoism
• It is natural for a person to demand his own
advantage, guided by reason.
“Since reason demands nothing contrary to Nature, it
demands that everyone…seek his own advantage.” (E4)
• Spinoza claims that men will be most useful to one
another, when each one seeks his own advantage.
26. Virtue Theory and Free Man
• “Free Man” is an individual who lives
according to the guidance of reason, is
passionless and has virtuous qualities.
• Practically it is impossible for humans to
become a “Free Man”.

28. Contractarianism
People “are often drawn in different directions and are contrary to one another, while they require
one another’s aid” (E4)
29. The Greatest Good
“Knowledge of God is the mind’s greatest good; its greatest virtue is to know God” (E4p28).

God

30. Conclusion
Spinoza’s philosophy can be viewed as the continuous reflection of role of knowledge. Although his
philosophy was a source of enormous controversy among philosophers and religious followers his work
has greatly impacted modern philosophy. Spinoza’s epistemology inculcates the different methods of
gaining knowledge as well as different types of knowledge that can help to use reasoning in order to
understand the indivisible nature of God. Spinoza’s moral philosophy is mainly based upon virtuous
ethics. He supported the concepts of ethical anti-realism, moral egoism and contractarianism. According
to him, the highest good is the knowledge of God, which leads to human blessedness.
