Science is distinguished as an element of our total contemporary culture, or “historical science,” from science as the professional business of natural scientists, or “experimental science.” Phenomenology has always taken a very critical stance against certain defects or biases -- objectivism, scientism, technicism -- it has found in historical science. It is my purpose to show that these defects and biases, associated historically with physical science, are not necessary parts of physical science, and consequently, that physics, especially experimental physics, has all of those hermeneutical, ontological, historical and dialectical dimensions negated by historical science. The notion of dialectic is given a formal logical construction as a time-dependent Q-lattice (Quantum-lattice or Quantum-logic), the form of which is suggested by quantum mechanics.

The following positions are then proposed and defended:

(1) Scientific states of affairs are given in an originary way to the experiencing scientist during the course of scientific observation.

(2) Scientific observation involves a special non-objective use of the instrument; one in which the noetic intention is embodied in the instrument joined, physically and intentionally, with the scientist; this non-objective use is characterized by a hermeneutical shift in the subject-object cut so as to place the instrument on the subject side of the cut, and the instrumental signals in a position of a “text” to be “read” in a “context.”

(3) Scientific experimentation in the fullest sense involves the possibility of a human subject embodying himself in instrumentation not only for the purposes of observation, but also to create that context, physical and noetic, which is the condition of possibility for the scientific object to manifest itself in observation.

(4) The historical fact of scientific revolutions confirms the hermeneutical aspect of experimental science and adds a dialectical movement to its history.

(5) In consequence of what has been said, we can outline the moments in the genetic constitution of scientific objects as elements of the life-world of the scientist; the scientist first learns the objective use of instrumentation, then, through acquired expertise, he passes to a non-objective use of instrumentation characterized by the following: intentional or subjective embodiment in instrumental artifacts, a hermeneutical shift in the subject-object cut, and the assimilation of instrumental signals to a text.

(6) Technological artifacts make possible modes of observational givenness which, unlike experimental science, are constituted by human technical interests; within this context scientific terms are used with analogical meanings.

(7) Quantum mechanics as a physical science gives a logical model, the Q-lattice, for the relation between context-dependent and dialectically related languages, that is, languages supposing relatively non-compossible modes of subjectivity.

(8) Quantum mechanics cannot be understood without recourse to a transcendental language that is the dialectical synthesis, in a Q-lattice, of physics and psychology.

(9) The hermeneutic aspects of natural science and technology have momentous consequences for the evolution of human subjectivity and the life-world.
