In the original concept "Homo Mensura" meant that "man is the measure of all things". In today;s society it seems to mean that "gay men are the measure of all things". Look at the proliferation of issues such as marriage, social security survivor rights, spousal rights to health care, and on and on.
No, Homo Mensura should not be redefined. The term is still very relevant in today's society and therefore should not be redefined. Homo Mensura means that man is the measure of all things, that everything is relative to human apprehension and evaluation, and that there is no objective truth. It is still used today and therefore no need to redefine.
No, Homo Mensura should not be redefined to be more hep for the culture of today, because it is already a modern philosophy. Homo Mensura believes that there is no truth that is universal, or that is complete truth. That is, that truth is relative to the experience of the person. This is a philosophy that many people believe today. Thus, it does not need to be redefined.
