Looking back on my childhood, I am convinced that naturalists are born and not made. Although we were all brought up in the same way, my brothers and sisters soon left their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental arithmetic.
Before World War I we spent our summer holidays in Hungary. I have only the dim(模糊的) memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm had led me into varied investigations（调查研究）. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious（清醒的） mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.
But curiosity, keen（敏锐的） eyes, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the excellent and essential qualities required is self-discipline, a quality I lack. A scientist, up to a certain point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.
