Overview
The word Philosophy comes from two Greek words, ‘Philos (love of) and Sophia (wisdom) so it literally means ‘the love of wisdom.’ Any philosophy is a system of belief(s).
The definition of philosophy typically, it is the study of ideas, or beliefs, to determine the fundamentals or meaning of a subject.
Philosophies typically address a subject matter systematically through rational or logical arguments and ideas, however, some that are considered philosophies do not follow such guidelines.
Types of Philosophies

Primary branches and foundational understanding have to be established in order to correctly develop any philosophical understanding. Some of the main areas of philosophy as applied to human understanding are:
- Epistemology – the study of knowledge
- Logic – the study of reasoning
- Metaphysics – the study of reality and how we relate to it
- Ethics – study of moral philosophies, understanding the best way to live
- Aesthetics – the study and understanding of beauty, art and sensual enjoyment
Many other branches exist but these 5 make up a basic understanding of how we interpret information around us, and are able to relate it to our existence.
Laws of First Principles or Causes
In order to conclude logic from any subject, the foundation must be set in order for the human mind to systematically make that conclusion.
The first principle is a basic foundational assumption that cannot be concluded from any other assumption, it becomes a prime statement.
Propositions or assumptions that are consistent with one another can produce statements that can be deducted from one another, for example:
LOGICAL ASSERTION: All men are mortal, Joe is a man, therefore Joe is mortal.

Criticism & Apologetics
Logic Dictates The Existence of God
First Philosophy – Philosophy of Principle and Cause
The great philosopher Aristotle was the first to identify the fact that in order for philosophy to even exist, the principle of ‘first cause’ must have already been in place. This means that in order for humans to identify logic or rationality, and to be able to systematically put ideas in order, a divine order must have first existed on which the order of rationality in our universe can be built upon.
The principle of ‘First Philosophy’ was identified as theology (study of God) even in ancient Greek times. This is because logic and rationality itself cannot account for its own existence, neither could logic come to existence by and random means. It must have some deeper integration and created order based on the fact that rationality can be systematically constructed and that logical matter must work together in order for any idea to even come into existence.
