Bacon, Boole, Biology, Basics Etc

"The Sensitive Man," VIII.

Michael Tighe of the Psychotechnics Institute expounds the origins of psychotechnics:

"'Francis Bacon speculated about a science of man. Boole did some work along those lines as well as inventing the symbolic logic which was to be a major tool in solving the problem." (p. 149)

As a philosophy undergraduate, I received an introduction to symbolic logic. However, googling "Boole Logic" brings up an article on "Boolean algebra" and I am struggling with how they connect. Symbolic logic merely formalizes consistency between propositions, e.g.:

If ((if p, then q) and p), then q -

- without any reference to the content of the propositions, just as, in algebra, letters like "x" and "y" can stand for any number. So I would want some further explanation as to how symbolic logic can be a major tool in developing psychotechnics.

Tighe continues. Freudian and subsequent psychologies:

"'...gave the first real notion of human semantics.'" (p. 149)

Did they?

Next:

human biology, chemistry and physics;
historical patterns recognized by Spengler, Pareto, Toynbee etc;
cybernetic homeostasis and feedback, applicable both to individuals and to societies;
games theory;
the principal of least effort;
"'...Haeml's generalized epistemology...'"; (ibid.)
(those last three imply basic laws and an analytical approach);
new logical and mathematical symbologies suggesting formulations for a rigorous symbolism to process data.

The Institute synthesized all this and I am no wiser.
