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).

Among the many written transitions available to writers, three basic Logical Transitions commonly 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.
