What is "addest"

Usage examples of "addest".

Indeed in the case of most pains let this remark of Epicurus aid thee, that pain is neither intolerable nor everlasting, if thou bearest in mind that it has its limits, and if thou addest nothing to it in imagination: and remember this too, that we do not perceive that many things which are disagreeable to us are the same as pain, such as excessive drowsiness, and the being scorched by heat, and the having no appetite.
