Logical Transitions connect premises together to form reasoned arguments.

Modular arguments support a single conclusion, but may contain MANY premises. The premises of an argument must be connected together to reasonably lead to a conclusion. How can premises be connected together?

Using straightforward "Logical Transitions" to connect premises together and to indicate conclusions can simplify and clarify scientific writing.

DEFINITION: "Logical Transitions" are words that indicate the logical relationships between separate elements of an argument (e.g. premises).

There are three basic Logical Transitions that can relate premises:

1. CONJUNCTIONS: Connecting premises that may both be true together into specific relationships.

2. DISJUNCTIONS: Separating premises into exclusive categories (both premises cannot be true).

3. CONCLUSIONS: Indicating the logical outcome of the premises.

The following sections review the basic logical transitions, and some of the many English words that can indicate each type of transition.
