The "Unix Philosophy" is a bankrupt romanticized after the fact rationalization to make up excuses and justifications for ridiculous ancient vestigial historic baggage like the lack of shared libraries and decent scripting languages, where you had to shell out THREE heavyweight processes -- "[" and "expr" and a sub-shell -- with an inexplicable flurry of punctuation [ "$(expr 1 + 1)" -eq 2 ] just to test if 1 + 1 = 2, even though the processor has single cycle instructions to add two numbers and test for equality.
