PDF [38] Now, the things we concern

[38] Now, the things we concern [39] ourselves with

[40] in science

[41,42] appear in a myriad of forms [43] and in a multitude of attributes.

[44] For instance, if you stand at the sea shore, [45] and look out, then you see, of [c]

[46] of course,

[47] the water, the waves breaking, [48] the foam,

[49] the slushing motion of water, the sounds [51] the air and the wind and the clouds

[52] and the sun and/on the blue sky and the light [53] and the sand and the rocks of various hardness, [54] permanence, color and texture.

[55] There're animals in the sea and sea weed.

[56] There's hunger and disease.

[57] There's been the observer standing on the beach.

[58] Maybe there is even happiness, and [th]

[59] thought.

[62] Any other spot

[63] in nature has a similar variety of [64] things

[65] and influences.

[66] It's always as complicated as that, no matter where you look.

[68] Curiosity demands that we ask question[s]

[69] and so we try to put things together [71,72] to understand this multitude of aspects

[73] as perhaps the action of a small number of elemental [74] things

[78] or things and forces perhaps in an infinite variety of combinations.

[79] For instance,

[80,81] Is the sand other than the rocks?

[82] that is to say,

[83] Is the sand maybe nothing but a great number of very tiny stone[s]?

[84] Is the moon a rock?

[86] Or we mean if we understood rocks, we also understand [87] the sand

[88] and the moon.
