Ab initio, a Latin term meaning “from the beginning,” is employed in a variety of contexts to signify that an analysis, process, or situation starts anew, without assumptions or influences from prior states or actions. The term is commonly used in different domains, including law, science, computing, and philosophy.
Usage in Different Domains
Legal Context
In legal parlance, “ab initio” is often used to describe situations, actions, or contracts that are considered void from the outset. For example, if a contract is deemed invalid “ab initio,” it means the agreement is treated as though it never existed.
Example: “The contract was declared void ab initio due to misrepresentation by one of the parties.”
Scientific Applications
In the scientific domain, particularly in computational chemistry and physics, “ab initio” methods refer to calculations or theories that are derived directly from basic physical laws without empirical or semi-empirical parameters.
Example: Ab initio molecular dynamics (AIMD) involves the direct computation of molecular properties using principles of quantum mechanics.
Information Technology
In computing, ab initio can refer to data processing or software engineering practices where systems or applications are built from scratch, without reliance on pre-existing codebases or structures.
Example: “The software was developed ab initio to ensure robust and scalable architecture.”
Philosophical Usage
Within philosophy, ab initio can be used to discuss arguments, theories, or discussions that are restarted or reconstructed from the foundational premises without any preconceived notions.
Example: “The philosopher approached the ethical dilemma ab initio, considering the fundamental principles of right and wrong.”
Mathematical and Physical Considerations
Where:
- \( E_{elec} \) is the electronic energy calculated based on quantum mechanical principles.
- \( E_{nuc} \) is the nuclear repulsion energy.
Historical Context
The use of “ab initio” dates back to classical Roman law and Latin literature, gaining prominence over centuries as Latin became the lingua franca for scholarly work across Europe. Today, it retains its relevance across multiple disciplines.

- De Novo: Latin for “from the new,” often used interchangeably with “ab initio” in scientific and legal contexts.
FAQs
Q: In what fields is the term ab initio most commonly used? A: Ab initio is most frequently employed in law, computational sciences like chemistry and physics, software development, and philosophical discourse.
Q: How does ab initio differ from de novo? A: “Ab initio” means starting from the very beginning, often implying a fundamental or root-level restart. “De novo” also implies starting anew but is often used when there is an element of renewal rather than a root-level initiation.
Q: Are there practical applications of ab initio methods in modern technology? A: Yes, particularly in materials science, drug design, and quantum computing, where ab initio methods enable precise modeling and simulations based on fundamental scientific principles.
Summary
Ab initio, meaning “from the beginning,” is a robust and versatile term used across various fields to denote an original or fundamental starting point, free from prior influences or assumptions. Its historical roots in Latin elevate its usage in academic, legal, scientific, and technological discussions, underscoring the importance of foundational analysis and purity in methodology.
