I disagree with pure "textualism", as it makes no attempt to discern original intent, or take into account changes in the commonly understood meanings of words.
"[W]hen a strict interpretation of the Constitution, according to the fixed rules which govern the interpretation of laws, is abandoned, and the theoretical opinions of individuals are allowed to control its meaning, we have no longer a Constitution; we are under the government of individual men, who for the time being have power to declare what the Constitution is, according to their own views of what it ought to mean." Dred Scott v. Sandford, 19 How. 393, 621 (1857) (Curtis, J., dissenting).
"On every question of construction [of the Constitution] let us carry ourselves back to the time when the Constitution was adopted, recollect the spirit manifested in the debates, and instead of trying what meaning may be squeezed out of the text, or intended against it, conform to the probable one in which it was passed."- Thomas Jefferson (1743-1826), letter to Judge William Johnson, (from Monticello, June 12, 1823) FOUNDER'S LIBRARY
"The Constitution was written to be understood by the voters; its words and phrases were used in their normal and ordinary, as distinguished from technical meaning; where the intention is clear, there is no room for construction, and no excuse for interpolation or addition." - Martin v.
