Making sense of senses !

One question which I always wanted to ask everyone is whether we see the same colour when we look at one. Is my 'red' the same as your 'red' ? Is it not possible that when each of us sees a certain colour, we do call it by the same name but our eyes see it in different hues ? What is red to me is also red to you - this I know. But my question is how can we be sure that the colour, that we both are proclaiming to be red, is not seen in different colours by us ? May be what we both see as 'red' is perceived by both of us differently. How can anyone prove or disprove that a colour appears the same to all of us ? How will you react if somehow you come to know that your school teacher or your mom, who taught you the names of colours, was perceiving the blue as you perceive green to be and what she perceives as green is how you see orange to be ?

That was about the eye. The same can be said about our experiences with the other sense organs. Is the taste 'sweet' same for all ? May be we all feel good while having something sweet because of the chemicals that get released inside our body owing to the molecule compounds in that food which render it sweet and yet taste sweetness differently. Do we all smell a certain fragrance in the same way ?

Another question : if we human beings were endowed with only four sense organs as against the current five, could we ever figure it out as to what we are lacking in ? Say if we all did not have ears, could we ever come to realise there is an attribute called 'sound' all around us but we could not sense it as the organ to sense sound - ears - is missing ? Now just think how many of such sense organs may already be missing in human beings and consequently we are deprived of sensing many attributes present around us. If we were able to sense those extra attributes, we might find our surroundings to be a place quite different from what we perceive it to be today.

human-made systems are bound to be imperfect

What I see around me are different organisations and systems working....many of them artificial, that is, human-made. These include society, family, education, marriage, politics, administration and what have you. Once we finish creating a system, we find ourselves or some of our brethren taking upon themselves the task of making it free from errors and limitations. This correction-making is a continuous and unending process : perfection cannot be achieved in these artificial systems. We can only endeavour to make them nearer to perfection. The day perfection is achieved, they will cease to exist. It is like that concept of Limits in mathematics wherein if x limits to zero, x will try to be as close as possible to zero but never equals zero, for then it will become meaningless.
We should rejoice in this fact rather than regretting it. This continuous struggle for excelling and ironing out the creases is what keeps us human beings engaged and gives many of us a purpose.
