### The Mathematics of Language and Thought, Volume 1

This substantial, two volume work, has taken 23 years to complete. It presents a new axiom based meta-language which unifies all branches of formal logic, probability theory, set theory, causality, and basic mathematics. It also describes the deep structure of natural language and natural human reasoning. Volume 1 provides the theory and Volume 2 the formal proofs.

The purpose of the book is to make formal logic and reasoning more accessible to non-specialists, and does so by providing a single, intuitive form of symbolism which can be manipulated in a similar manner to algebra. Unlike algebra, however, only the rules of the meta-language itself, and none from other systems, are used in this manipulation. The language lies, therefore, at the foundation of human reasoning.

The meta-language contains several innovations. It treats everything as a bounded entity in space-time, i.e., as a system, including relationships and information. It also improves on conventional set theory, tense logic, epistemic logic, and complex causality. Importantly, it offers a means of manipulating qualitative concepts such as those found in the social sciences, as well as the quantitative concepts to which conventional mathematics is applied.

### The Mathematics of Language and Thought, Volume 2

This book contains the mathematical proofs in support of Volume 1

**A Systems Model of Human Organisation**

This short monograph describes a model of human society based on the principles of general systems theory. The model can help us to understand human interaction at all levels. It can also be used to identify behavioural changes which might lead to social improvements such as the prevention of conflict and the alleviation of poverty.

**A Systems Model of Leadership and Followership**

This monograph follows on from A Systems Model of Human Organisation. It describes the processes involved in the command or leadership components and in subordinate or follower components of human society. It recommended that it be read in conjunction with the two sets of diagrams below which support it.

**Logic Causality and Systems**

This set of Powerpoint slides describes a means of translating systems and causal processes into symbolic logic.

**Leader & Follower Process Diagrams**

This is a set of A3 causality diagrams which illustrate the processes described in “A Systems Model o the processes involved set of A3 diagrams.

**Rational Understanding – Articles 1 to 42**

On 4th June, 2022, I had been posting at Rational-Understanding.com for a year. This first year’s articles are combined here into a small booklet.

**Joining Up the Dots**

This article looks at the similarities between various concepts in Systems Theory, Causality and Logic and identifies a common theme.

**How Organisations and Hierarchies Arise**

Articles 53 to 70 combined to form a single pdf document.

**How to Reunite a Nation**

This articles offers a solution to divisive politics in the USA.
