On Ho's "modern logic and schizophrenic thinking"

The purpose of this note is to point out that conclusions drawn in the title paper about the role of logic in the schizophrenia thought process are not reliable, since they are based on patients medicated with antipsychotic drugs. The substance of this note is drawn from the title paper and related literature. The principal conclusion is that Dr. Ho's deductions about the role of logic in schizophrenia follow only if one confuses psychiatric diagnosis with psychotic behavior.
