Some countries and some people are so primitively religious and so underdeveloped that they don't need a time machine to go back to the past; they are already in there, in the very distant and dark past!

Stick to life, just like a baby sticking to a candy!

Humanity must have a speed of advance higher than the speed of advance of cosmic disasters or big global catastrophes!

Fame is a devil; obscurity is an Angel! Stay away from me, Devil; Come near to me, Angel!

When you long for the port, it is time to leave the journey; when you long for the journey, it is time to leave the port!

Idealists are not the good friends of the truths; they create their own truth.

Here is the best wish for the new year: Let there be more freedom of thought throughout the world! Fields need rain; truths need freedom of thought!
