It is very difficult to distinguish between a false and a true ideal. It is not only difficult, but it is impossible; for if something is false, then it is as false as it is real; and if it is real, it is as real as it is false. The best way is just to take as true that which at the time appears true to us. But we should not always discuss it with others, nor try to defend it. We do not know. We do not know if what we find true today will not appear false to us tomorrow; for all these terms, good or bad, right or wrong, virtue or sin, false or true, are relative; and according to differences of time and space they change, which means that it depends from what height we look at it, from what position we see it. In other words, what seems right in the morning, may seem wrong in the evening, and what may seem wrong in the day, may seem right at night. Another example is that if we stand on a certain step of a staircase when looking at things, the right things will seem wrong by looking at them from another step; and the wrong, things will seem right by looking at them from a higher or lower one. Therefore whatever we consider at the time to be right, just, good, and virtuous, that is the thing we ought to do; but we should not impose or urge what we consider right or good or true upon others who do not consider it in the same way as we do.
