Edmund Gustav Albrecht Husserl 8 April 1859 – 27 April 1938) was a German philosopher who established the school of phenomenology. In his early work, he elaborated critiques of historicism and of psychologism in logic based on analyses of intentionality. In his mature work, he sought to develop a systematic foundational science based on the so-called phenomenological reduction. Arguing that transcendental consciousness sets the limits of all possible knowledge, Husserl redefined phenomenology as a transcendental-idealist philosophy. Husserl's thought profoundly influenced the landscape of 20th-century philosophy, and he remains a notable figure in contemporary philosophy and beyond.

A principal intention of this essay is to separate what are known as algebras of logic from the subject of logic, and to re-align them with mathematics. Such algebras, commonly called Boolean, appear mysterious because accounts of their properties at present reveal nothing of any mathematical interest about their arithmetics.
