Cosmology
2.1 Corruption of one thing is the generation of another thing.

Psychology:
3.1 Nothing is in the intellect which is not first in the senses.
3.2 An inclination follows every form.

3.7 Whatever is received, is received in the mode of the receiver.
3.8 The intellect in act is the intelligible object in act.

3.10 Good is self diffusing.
3.11 Something is knowable insofar as it is in act.

Metaphysics:
Act-Potency:
4.1 "To act” follows "to be." Action follows (and manifests) the being of something.
4.2 There is no third way, there can be no middle between being and nonbeing.
4.3 The potency is ordained to its act and is specified by its object.
4.4 What is in potency, is not reduced to act except by a being already in act.
4.5 It is of the nature of act to communicate itself insofar as it is able.
4.6 The more distant a potency is from act, the more powerful an agent must be to actuate it.
Essence-Existence:
5.1 Through the form the existence comes to a thing (Form gives being).
5.2 Each agent acts through its form.
5.3 Each agent produces an effect similar.
5.4 No created substance is operating per se (by itself).
5.5 What is "per accidens" is accidental to that which is “per se." (i.e. accidental presupposes essential, see [6.19]).
Causality:
6.1 Whatever is moved is moved by another.
6.2 Nothing comes from nothing.
6.3 Every agent acts on account of an end.
6.4 The cause is greater than the effect.
6.5 Nothing is the cause of itself.
6.6 Causes are the causes of one another (in different lines of causality).
6.7 The cause of the cause) is the cause of the thing caused.
6.8 Take away the cause and you take away the effect.
6.9 If you have an effects you have necessarily a cause.
6.10 The end is the cause of causes.
6.11 The end is first in intention and last in execution.
6.12 Whoever desires the ends desires the means to that end.
6.13 It is the proper of the most perfect cause to give the dignity of secondary cause to imperfect effects.
6.14 A multitude does not have in itself the reason of its unity.
6.15 What is composed does not have in itself the reason of its unity.
6.16 Nothing acts unless insofar as it is in act.
6.17 The order of ends corresponds to the order of agents.
6.18 The corruption of the best is the worst (e.g. corruption of the prince or of the principles).
6.19 What is essential is prior to that which is accidental.
6.20 What is by participation is caused by that which is by essence.
6.21 No one can give what he does not have.
6.22 The higher the natures the more intimate is what flows from it.
6.23 It is the proper of the best to make the best.
6.24 The way someone is is the way he determines what end is convenient for him.
6.25 What can not be, sometimes is not.
6.26 What can be deficient sometimes is deficient.
6.27 Being (and miracles) must not be multiplied.
6.28 What is supreme in a genus is cause of everything in the genus.
6.29 What can be done by few principles is not done by many.
6.30 The part and the whole are the same regarding the end.

First Principles of Reason:
7.1 Sufficient reason: Everything has sufficient reason of being either in itself or in another.
7.2 Identity: Every being is by itself constituted in its own specific nature.
7.3 Non‑contradiction: One and the same being cannot be and not be what it is.
7.4 Contraries: One and the same being cannot be and not be at the same time and in the same sense determined in two different ways.
7.5 Causality: Every being which can not‑be needs an efficient cause to be.
7.6 Finality: Every agent acts for an end.
7.7 The same causes in the same circumstances produce always the same effects. |
